feat(extras): Add extra for angular lspconfig (#2806)

* 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
