PY-72185 Use PythonHighlightingLexer instead of plain Python lexer in reparse check of PyReparseableIdentifier

Browse Source 
The problem previously appeared in situations when an identifier was changed to a keyword, i.e. `a: Tru` -> `a: True` and `True` keyword was not highlighted properly as it was substituted by an identifier AST leaf as is bypassing the highlighting lexer

Add a couple of tests on it
