P2582R1 CTAD from inherited constructors is missing a feature-test macro bump

[ppalka-rh]

Perhaps __cpp_deduction_guides should be bumped to 202207L after the adoption of #5581 for C++23?

I think this should be handled by a CWG issue. Opened cplusplus/CWG#795.

P1. An incorrect value for a feature-test macro is a normative issue.

cplusplus/CWG#795 (comment) The editors agreed that this can be resolved editorially.
