feat(diagnostic): add suffix option to virt_text config (#21140)

Browse Source 
This introduces a `suffix` option to the `virt_text` config in
`vim.diagnostic.config()`. The suffix can either be a string which is appended
to the diagnostic message or a function returning such. The function receives a
`diagnostic` argument, which is the diagnostic table of the last diagnostic (the
one whose message is rendered as virt text).
