feat: alias :LspInfo to `:checkhealth vim.lsp` #3663

Problem:
`:checkhealth lspconfig` has no benefits vs `:checkhealth vim.lsp`.

Solution:
- on Nvim 0.11+, `:LspInfo` is an alias to `:checkhealth vim.lsp`
  instead of `:checkhealth lspconfig`.
- `lua/lspconfig/health.lua` will be removed in a few months.
