feat: add mips assembly grammar

[parksb]

• Add a test if possible
• Format all commit messages with Conventional Commits
• I have read docs for adding a language.
• I have searched around and this is the most up-to-date, actively maintained version of the language grammar.
• I have added a sample file that includes a variety of language syntaxes and succinctly captures the idiosyncrasy of a language. See docs for requirement.

Can we name it with the id mips and use mipsasm as the alias?

Hey, thanks for your contribution! With the recent rewrite of v1.0, we have moved the grammars out of this repository. We generally suggest you loading the grammar locally to move forward. If you believe this is the language that is widely used, you can send an issue or PR to this repo: https://github.com/shikijs/textmate-grammars-themes

Thank you!
