feat: more languages supported

I'd like to expand the number of languages supported for comment checking. There are a number of additional considerations for structured comments (like JavaDoc), but some should be pretty straightforward.

Running list:

• Bash
• YAML
• HTML
• Java
• Groovy
• Git commit buffers (filetype gitcommit)
• PowerShell

In addition to adding language parsers to the tree-sitter code, we would also need to open pull requests for nvim-lspconfig, mason and fix harper-ls to announce support for the capability.

Feel free to add suggestions to this list.
