feat(parser): register common short-hand as filetypes

Browse source 
Problem: Cannot use short-hands for @injection.language (e.g., `py` for
Python).

Solution: Register common short-hand as filetypes for some languages.

List taken from https://github.com/helix-editor/helix/blob/master/languages.toml

Also remove deprecation custom filetype->parser mapping.
