[Bug] Can't set pcss as extension

[equinusocio]

Describe the bug
Whle #15 seems to be fixed, I'm not able to assign pcss to the config array, even is is a perfect valid postcss extension suggested for any postcss file since enables vscode completation, stylelint validations and postcss plugin support.

To Reproduce
Steps to reproduce the behavior:

1. Add this to vscode config

  "cssvar.extensions": [
    "css", "pcss", "jsx", "tsx"
  ],

Expected behavior
No warning about pcss extensions

Screenshots

Additional Info

Some of the accepted values are not extensions at all, like postcss and stylus are not file extensions, they are language IDs and their relative extensions are .pcss and .styl. Language IDs and file extensions are two completely different things in vscode.

Warning
By adding postcss to the list it works for all files using postcss id, indipendently from their extension. It looks like a mispelled setting name since seems to work with languages and not file extensions

Solution

Rename cssvar.extensions into cssvar.languages or make it work with file extensions and not language IDs.

Agreed!!

The config name was chosen initially to point only extension names, but the code has changed a lot and for backwards compatibility I never renamed it.

I will take a look into this once I am back.
If you want to work on it please feel free to open a PR.☺️

Thanks for raising this concern 👍
