Describe the feature

Inspired by discussion in zed-industries/extensions#746

The problem

Now the only way to choose a language for file is path_suffix configuration option in

zed/crates/language/src/language.rs

Line 616 in 7cef5b2

pub struct LanguageMatcher {

. Sometimes the language to use is not determined by file's extension but file's location or it's name.

Proposed fix

Extend LanguageMatcher with path_globs field with a list of globs matching file path.

If applicable, add mockups / screenshots to help present your vision of the feature
