Limit matches of treesit-thing-settings in js-ts-mode (bug#71244)

Browse source 
* lisp/progmodes/js.el (js-ts-mode): Use 'js--regexp-opt-symbol'
for 'js--treesit-sexp-nodes', 'js--treesit-sentence-nodes' and 'text'
that wraps the regexp in \_< and \_> delimiters to avoid false positives
such as "expression" used for "expression_statement".
(js--treesit-sexp-nodes): Add more useful nodes "parenthesized_expression",
"formal_parameters", "statement_block", "object", "object_pattern",
"named_imports", "class_body".
