Subject: [PATCH] Update JSX support due to upstream changes (bug#64647)

A recent change in tree-sitter-javascript grammar support for
JSX (commit bb1f97b), changed two things:
1. renamed nested_identifier to member_expression
2. removed jsx_fragment, jsx_text is used instead

* lisp/progmodes/js.el (js-jsx--treesit-indent-compatibility-bb1f97b):
Indent helper function to handle different tree-sitter-javascript
version.
* lisp/progmodes/js.el (js--treesit-indent-rules): Use the new
function to handle both jsx_fragment and jsx_text.
* lisp/progmodes/js.el (js-jsx--treesit-font-lock-compatibility-bb1f97b):
Font lock helper function for handle different tree-sitter-javascript
version.
* lisp/progmodes/js.el (js--treesit-font-lock-settings): Use the new
function to handle both nested_identifier and member_expression.
