chore: try nvm to install node on wsl

[AndyOGo]

fixes #2737

Try to install node with nvm as suggested here:
https://learn.microsoft.com/en-us/windows/dev-environment/javascript/nodejs-on-wsl#install-nvm-nodejs-and-npm

[AndyOGo]

That didn't succeed...

wsl : Cloning into '/home/appveyor/.nvm'...

Fails again...

https://ci.appveyor.com/project/ljharb/eslint-plugin-import/builds/46533693/job/1kvv7b5dqps3kg5b#L33

bash: line 137: unexpected EOF while looking for matching `}'
bash: line 138: syntax error: unexpected end of file
Command exited with code 2

(please keep reusing this PR for future attempts, rather than opening up a new one)

That particular failure indicates the script didn't download in its entirety.

@ljharb I needed to pipe it through dos2unix 🤨

I will try to touch ~/.bash_profile for the next error...

https://ci.appveyor.com/project/ljharb/eslint-plugin-import/builds/46535646/job/evt689nv4sdsfnw2#L77

=> Profile not found. Tried ~/.bashrc, ~/.bash_profile, ~/.zprofile, ~/.zshrc, and ~/.profile.
=> Create one of them and run this script again
   OR
=> Append the following lines to the correct file yourself:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

@ljharb
Sorry, I give up.
I assumed it would be straight-forward to follow this guide to get node running inside WSL
https://learn.microsoft.com/en-us/windows/dev-environment/javascript/nodejs-on-wsl#install-nvm-nodejs-and-npm

But man, was I wrong...

• ps: fails with NativeCommandError if a command outputs to STDERR
  • https://help.appveyor.com/discussions/problems/5413-calling-external-executable-causes-nativecommanderror-despite-no-apparent-error
  • curl -s needs to be silenced
  • E.g git clone 2>&1 outputs non-errors to STDERR and needs to be redirected - fore that reason I needed to fork nvm
• appveyor doesn't seem to support nodejs for WSL
  https://www.appveyor.com/docs/lang/nodejs-iojs/
• Actually that's all I can find about WSL on appveyor 🤨

Thanks for trying.
