Make lsp-ansible work on yaml-ts-mode buffers (#4052)

yaml-ts-mode derives from text-mode, so `(derived-mode-p 'yaml-mode)` returns
`nil`.

```emacs-lisp
(define-derived-mode yaml-ts-mode text-mode "YAML"
  "Major mode for editing YAML, powered by tree-sitter."
  :group 'yaml
  :syntax-table yaml-ts-mode--syntax-table
  [...])
```
