fix(lsp): warn on missing config in :checkhealth #33087

Browse Source 
Problem
When calling `:checkhealth vim.lsp` after the user has enabled a language
server with `vim.lsp.enable` that has no configuration a runtime error
is hit because the code expects for a configuration to exist.

Solution:
Check if a configuration was returned before parsing it, if it isn't
returned then warn the user that the server has been enabled but a
configuration was not found.
