Open a JavaScript file containing 'const x = 10;' for instance. Then,
enable js-ts-mode (M-x js-ts-mode). Expected the literal '10' to be
highlighted with font-lock-number-face, but it is not.

The apparent reason is that the 'function' node name used in
treesit-font-lock-rules to define js--treesit-font-lock-settings (in the
file js.el) is a valid elisp function (C-h f function). This invalidates
the query, as verified by running the following:

(treesit-query-validate 'javascript ((function
      name: (identifier) @font-lock-function-name-face)

     (class_declaration
      name: (identifier) @font-lock-type-face)

     (function_declaration
      name: (identifier) @font-lock-function-name-face)

     (method_definition
      name: (property_identifier) @font-lock-function-name-face)

     (formal_parameters
      [(identifier) @font-lock-variable-name-face
       (array_pattern (identifier) @font-lock-variable-name-face)
       (object_pattern (shorthand_property_identifier_pattern)
@font-lock-variable-name-face)])

     (variable_declarator
      name: (identifier) @font-lock-variable-name-face)

     (variable_declarator
      name: (identifier) @font-lock-function-name-face
      value: [(function) (arrow_function)])

     (variable_declarator
      name: [(array_pattern (identifier) @font-lock-variable-name-face)
             (object_pattern
              (shorthand_property_identifier_pattern)
@font-lock-variable-name-face)])

     ;; full module imports
     (import_clause (identifier) @font-lock-variable-name-face)
     ;; named imports with aliasing
     (import_clause (named_imports (import_specifier
                                    alias: (identifier)
@font-lock-variable-name-face)))
     ;; named imports without aliasing
     (import_clause (named_imports (import_specifier
                                    !alias
                                    name: (identifier)
@font-lock-variable-name-face)))

     ;; full namespace import (* as alias)
     (import_clause (namespace_import (identifier)
     @font-lock-variable-name-face))))

Note that this query is taken directly from the definition of
js--tresit-font-lock-settings.

Removing the invalid snippet above from the definition of
js--treesit-font-lock-settings fixes this bug.
