Only warn of parsers needed by the current filetype

The documentation and :checkhealth r only require the r parser, but we check for most parsers on startup. With this pull request, we only check for the parsers required by the current file type.

:RDebugInfo was failing to correctly detect the language in the YAML header of a Quarto document as yaml and normal text as markdown_inline. I deleted these two checks.

Just one small thing

When v is the missing parser, table.concat(needed, ...) still concatenates the entire needed list, not just the missing one. ie. all parser in the table will be printed. I think?

[jalvesaq]

Initially, the needed is only {"r"}. The other parsers are inserted into the table according to the current value of filetype. So, they are all needed for the specific file being edited.

All good! Just this message, I think it will print all the needed parsers, not just the missing one.

I see your point now. It might be better to be specific and warn about the missing one that triggered the warning.

[PMassicotte]

All good with me, maybe ok also to print all. I do not have preference in fact. Lets merge it?

Thank you 👍
