Subject: feat: force-stop server with :LspStop! (bang) #4140

Problem:
Some servers don't stop properly.

Calling `:LspStop` _twice_ will induce a force-stop, but that is not easy to
discover: https://github.com/neovim/neovim/blob/b67eff38fe19876ab228007897224ec04b58aa40/runtime/lua/vim/lsp/client.lua#L864-L866
> By default, it will just request the server to shutdown without force. If
> you request to stop a client which has previously been requested to
> shutdown, it will automatically escalate and force shutdown.

Solution:
Nvim should automatically force-stop after X seconds, but until that is
supported, adding a bang "!" variant is reasonable.
