## Problem
Sometimes angular treesitter didn't get started, e.g. when creating a
new file.
## Solution
- Add `BufNew` event to attach angular treesitter.
- Change `BufRead` to `BufReadPost` for better readability.

## Problem
Treesitter was not working in angular html templates after enabling
`lang.angular` extra.
## Solution
Added a change recommeded by angular treesitter developer to enable
treesitter for components and containers.

* feat(extras): Add extra for angular lspconfig
Since treesitter has better support for angular parser recently that works for the legacy and the latest version of it,
I am happy to suggest this extra configuration that works for well for me without any issue.
And since lack of references about how to config the angular lsp inside of neovim out there, this will work fine as a starting point.
* feat(extras): Added `angularls` lsp configuration
* feat(extras.lang): update `angularls` configuration
