Describe the bug

As indicated here 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

I've created a PR but for others bumping into this you can also do the following workaround:
Create an auto command that will set the filetype to html.htmlangular

local autoCommands = vim.api.nvim_create_augroup("autoCommands", { clear = true })
vim.api.nvim_create_autocmd(
  { "BufRead", "BufNewFile" },
  { group = autoCommands, pattern = "*.component.html", command = "set filetype=html" }
)

However that will leave you without the nice highlighting of treesitter (if you are using that) in which case you can:
Create an auto command that will set the filetype to html.htmlangular (which essentially sets 2 file types, html and htmlangular) and extend the treesitter language to include that filetype so you still have the highlighting.

vim.treesitter.language.register("angular", "html.htmlangular")

local autoCommands = vim.api.nvim_create_augroup("autoCommands", { clear = true })
vim.api.nvim_create_autocmd(
  { "BufRead", "BufNewFile" },
  { group = autoCommands, pattern = "*.component.html", command = "set filetype=html.htmlangular" }
)
