Update Alpine instructions (#7156)
While trying to set up code-server on Alpine, I ran into build errors. To solve them, I had to add Kerberos development libs. Also, it looks like npm config doesn't work in recent version of Node and doesn't seem to be necessary. These instructions were tested in the Docker `node:20-alpine` image.

If you're installing code-server via `npm`, you'll need to install additional
dependencies required to build the native modules used by VS Code. This article
includes installing instructions based on your operating system.
> **WARNING**: Do not use `yarn` to install code-server. Unlike `npm`, it does not respect
> lockfiles for distributed applications. It will instead use the latest version
> available at installation time - which might not be the one used for a given
> code-server release, and [might lead to unexpected behavior](https://github.com/coder/code-server/issues/4927).
## Node.js version
We use the same major version of Node.js shipped with Code's remote, which is
currently `20.x`. VS Code also [lists Node.js
requirements](https://github.com/microsoft/vscode/wiki/How-to-Contribute#prerequisites).
Using other versions of Node.js [may lead to unexpected
behavior](https://github.com/coder/code-server/issues/1633).
## Ubuntu, Debian
```bash
sudo apt-get install -y \
build-essential \
pkg-config \
python3
npm config set python python3
```
Proceed to [installing](#installing)
## Fedora, CentOS, RHEL
```bash
sudo yum groupinstall -y 'Development Tools'
sudo yum config-manager --set-enabled PowerTools # unnecessary on CentOS 7
sudo yum install -y python2
npm config set python python2
```
Proceed to [installing](#installing)
## Alpine
```bash
apk add alpine-sdk bash libstdc++ libc6-compat python3 krb5-dev
```
Proceed to [installing](#installing)
## macOS
```bash
xcode-select --install
```
Proceed to [installing](#installing)
## FreeBSD
```sh
pkg install -y git python npm-node20 pkgconf
pkg install -y libinotify
```
Proceed to [installing](#installing)
## Windows
Installing code-server requires all of the [prerequisites for VS Code development](https://github.com/Microsoft/vscode/wiki/How-to-Contribute#prerequisites). When installing the C++ compiler tool chain, we recommend using "Option 2: Visual Studio 2019" for best results.
Next, install code-server with:
```bash
npm install --global code-server
code-server
# Now visit http://127.0.0.1:8080. Your password is in ~/.config/code-server/config.yaml
```
A `postinstall.sh` script will attempt to run. Select your terminal (e.g., Git bash) as the default shell for npm run-scripts. If an additional dialog does not appear, run the install command again.
If the `code-server` command is not found, you'll need to [add a directory to your PATH](https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/). To find the directory, use the following command:
```shell
npm config get prefix
```
For help and additional troubleshooting, see [#1397](https://github.com/coder/code-server/issues/1397).
## Installing
After adding the dependencies for your OS, install the code-server package globally:
```bash
npm install --global code-server
code-server
# Now visit http://127.0.0.1:8080. Your password is in ~/.config/code-server/config.yaml
```

### Issues with Node.js after version upgrades
Occasionally, you may run into issues with Node.js.
If you install code-server using `npm`, and you upgrade your Node.js
version, you may need to reinstall code-server to recompile native modules.
Sometimes, you can get around this by navigating into code-server's `lib/vscode`
directory and running `npm rebuild` to recompile the modules.
A step-by-step example of how you might do this is:
1. Install code-server: `brew install code-server`
2. Navigate into the directory: `cd /usr/local/Cellar/code-server/<version>/libexec/lib/vscode/`
3. Recompile the native modules: `npm rebuild`
4. Restart code-server
### Debugging install issues with npm
To debug installation issues, install with `npm`:
```shell
# Uninstall
npm uninstall --global code-server > /dev/null 2>&1
# Install with logging
npm install --loglevel verbose --global code-server
```
