allow .pcss as a extension for postcss files

[lucidlemon]

This would allow css files to not only end in .m.css and .css but also .m.pcss and .pcss in order to interpret postcss files as such within the IDE.

I hope these changes are 100% correct, for some reason there are a total of 7 definitions for .css files in here - is this intended?

As this shouldn't break existing code I guess this could be merged quite quickly.

why is a merge request failing if the codecov stays exactly the same? 🤔

It was running the tests when you checked.

Please see my last two notes in #89. I'd like to make 100% certain we're fixing this in the right place and fully understand the problem before we land this. Also note that we would need to also solve this for cli-build-widget as well, assuming we go this route.
