6a07dd22 - [syntax-errors] Fix multiple assignment for class keyword argument (#17184)

[syntax-errors] Fix multiple assignment for class keyword argument (#17184) Summary -- Fixes #17181. The cases being tested with multiple *keys* being equal are actually a slightly different error, more like the error for `MatchMapping` than like the other multiple assignment errors: ```pycon >>> match x: ... case Class(x=x, x=x): ... ... File "<python-input-249>", line 2 case Class(x=x, x=x): ... ^ SyntaxError: attribute name repeated in class pattern: x >>> match x: ... case {"x": 1, "x": 2}: ... ... File "<python-input-251>", line 2 case {"x": 1, "x": 2}: ... ^^^^^^^^^^^^^^^^ SyntaxError: mapping pattern checks duplicate key ('x') >>> match x: ... case [x, x]: ... ... File "<python-input-252>", line 2 case [x, x]: ... ^ SyntaxError: multiple assignments to name 'x' in pattern ``` This PR just stops the false positive reported in the issue, but I will quickly follow it up with a new rule (or possibly combined with the mapping rule) catching the repeated attributes separately. Test Plan -- New inline `test_ok` and updating the `test_err` cases to have duplicate values instead of keys.
