## Describe the bug

As indicated [here](https://github.com/dlvandenberg/tree-sitter-angular?tab=readme-ov-file#filetype) Neovim is now detecting file-types for angular and sets a filetype of `htmlangular`. Currently coc-angular looks for `html` or `typescript`, hence the plugins is not activated.

## Reproduce the bug
- Use "the nightly neovim built (or release 0.11.x)"
- Open an angular project
- Attempt to use the coc-angular functionalities in a component template
- Notice the functionality does not work in the template, but works in the typescript code
