Update TSX support due to upstream changes (bug#64647)

A recent change in tree-sitter-typescript grammar support for
TSX (commit b893426), changed two things:
1. renamed nested_identifier to member_expression
2. removed jsx_fragment, jsx_text is used instead

* lisp/progmodes/typescript-ts-mode.el
(tsx-ts-mode--indent-compatibility-b893426): Indent helper function
to handle different tree-sitter-typescript version.
* lisp/progmodes/typescript-ts-mode.el
(typescript-ts-mode--indent-rules): use the new function to handle
both jsx_fragment and jsx_text.
* lisp/progmodes/typescript-ts-mode.el
(tsx-ts-mode--font-lock-compatibility-bb1f97b): Font lock helper
function for handle different tree-sitter-typescript version.
* lisp/progmodes/typescript-ts-mode.el
(typescript-ts-mode--font-lock-settings): Use the new function to
handle both nested_identifier and member_expression.
