Migrating Zig linguist to new repo

Zig [migrated from GitHub to Codeberg](https://ziglang.org/news/migrating-from-github-to-codeberg/), this includes the [sublime-zig-language](https://codeberg.org/ziglang/sublime-zig-language) repo.

Currently they are both on the same commit because the repo has been unmaintained however there is some work being done on updating the TextMate grammar which linguist would benefit from however I am unaware/unsure if linguist should / is allowed to pull in repos from third-party services.

Just looking for feedback on the matter
