Remove snippet language inheritance

[AndreasArvidsson]

Today in snippets we inherit snippet from one language to another. For example typescript inherits all javascript snippets.

This behavior is defined here:

community/core/snippets/snippets.py

Lines 126 to 147 in b57dac8

	def get_super_languages(language: str) -> list[str]:
	"""Returns a list of languages that are considered a superset of <language>, including <language> itself. Eg `javascript` will be included in the list when <language> is `typescript`.
	Note that the order of languages returned here is very important: more general must precede more specific, so that specific langs can properly override general languages.
	"""
	match language:
	case "_":
	return ["_"]
	case "typescript":
	return ["_", "javascript", "typescript"]
	case "javascriptreact":
	return ["_", "html", "javascript", "javascriptreact"]
	case "typescriptreact":
	return [
	"_",
	"html",
	"javascript",
	"typescript",
	"javascriptreact",
	"typescriptreact",
	]
	case _:
	return ["_", language]

This was made in an effort to make the snippet files as small as possible. In hindsight this was a bad decision. First of all is not at all obvious to users which languages are inherited and there is no simple way for them to extend this list. I recommend that we remove this and update the snippet files to just explicitly include all languages that are needed.
