@MarcoGorelli, could you please take a look at this PR? It's a follow-up of PR: "DEPR offsets: rename 'M' to 'ME'".
seems like ci failure isn't related to my changes looks like there's some test failures
```

`test_read_json_table_period_orient` failed because there was a bug for conversion JSON field descriptor into pandas type for deprecated offsets frequency 'M'. We fixed it in #55581, now the test passes.

I added parameters `'Q'` and `'2Q'` into parametrization of `test_read_json_table_orient_period_depr_freq` thanks @natmokval !
