option for auto-install lsp

[matan-h]

now, when the user want to use helix, he need to look at How to install the default language servers on the GitHub wiki,then use hx --health for check if lsp is installed,then install it,then maybe add it to $PATH.
maybe helix can prompt the user for auto-install the lsp of the file. (or point to the wiki)

like prompt:

do you want to install recommended lsp for python (python-lsp-server) using pipx? [y/N]

Pointing to the wiki seems like a good idea, but installing the server itself would be too big a burden maintenance wise. Maybe plugins in the future can solve this with "bundles" for languages.

I don't know how to commit to my fork, without adding it to existing pr,so I delete it right after,but I made simple println of wiki link in checkhealth at a1bec0a

https://github.com/williamboman/nvim-lsp-installer/ contains all the logic to install all the language servers, it could be converted to a bash script for universal use.
