feat(angular): Migrate to built-in treesitter

[dzonatan]

https://github.com/nvim-treesitter/nvim-treesitter-angular is deprecated (and archived) since Angular support is included in nvim-treesitter itself.

Without this fix, currently running :TSUpdate angular fails with:

nvim-treesitter[angular]: Error during tarball extraction.                                                                                                                                     
tar: Error opening archive: Unrecognized archive format  

It almost seems unrelated, but it is nvim-treesitter/nvim-treesitter#5246

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Proper usage of opts table rather than setting things up with the config function.

@dzonatan Can you see if they’re fixed the JSX issues that the fork fixed?

[dzonatan]

Can't reproduce so I guess it's fine.
Also, at some point the "fix" was merged into the main repo nvim-treesitter/nvim-treesitter-angular#4
