feat(buf): new lsp for protobuf

[gogamid]

As may know, bufbuild team is working on the new lsp for protobufs which is included in the cli itself. Compared to buf-language-server, this lsp supports more features. Take a look at this PR for more info. This config sets up the new buf lsp.

Thanks for posting this!

qq: are you having problems with the LSP timing out and exiting? When I was playing with this I had to set --timeout=0 or the LSP would exit.
I'd also suggest adding --log-format=text. The default is color and it makes the logs hard to read

@sprsquish yeah, i got occasional crash, i thought because the lsp is still in beta phase. But good suggestions!

the old bufls can mark as deprecated ? and current server file name is a bit confusing. I think it is better to use xx_ls.lua as the file name if there is no special server command name.

https://github.com/bufbuild/buf-language-server this repo is archived so could you also add a deprecate of bufls in lua/lspconfig.lua aliases table ?
