This fixes the annoying error shown on the import line
Cannot resolve directory 'node_modules' less... (Strg+F1)
This inspection checks references to files and directories.
Sass compilers can sometimes be weird if import urls like this aren't quoted. They'll spit out junk like
```
Error: Encountered invalid @import syntax.
```
Anyways, pretty common practice to use quotes for all imports. I mean, seriously, how much more do you want me to write for a dang PR that adds a pair of quotes? I've got work to do, gah.
