Subject: bug#60453: 29.0.60; treesit-range-rules throw an error without tree-sitter

With the following code without tree-sitter library:

(defvar elixir-ts-mode--treesit-range-rules
  (treesit-range-rules
   :embed 'heex
   :host 'elixir
   '((sigil (sigil_name) @name (:match "^[H]$" @name) 
   (quoted_content)
  @heex))))

upon loading the mode I get the following error:

treesit-range-rules: Symbol’s function definition is void:
treesit-query-compile

This can easily be mitigated with (when (treesit-available-p)...) 
but
think it should function similar to how (treesit-font-lock-rules 
work.
