I guess there are two prerequisites that need to be completed before that:

• Add it to https://github.com/mason-org/mason-registry
• Add it to https://github.com/neovim/nvim-lspconfig

I noticed that https://github.com/rcjsuen/dockerfile-language-server with the same name already exists, which is interesting. I'm not sure how that should be handled since the new LSP is the official one.

That's not the same name. One is docker-language-server and one is dockerfile-language-server
