Summary

• Document how the region argument maps to locale subtags listed on the supported locales page, with en-IN and fr-CA examples.
• Reuse the parser's current month when applying PREFER_MONTH_OF_YEAR="current" to incomplete dates, so current month and current day come from the same relative base.
• Add a regression test for the month-boundary case where UTC is still May 31 but the local CI timezone is already June 1.

Fixes #465.

Pull request overview

Adds a short explanatory note to the supported locales documentation page clarifying how the region argument relates to the locale codes listed in the table, addressing user confusion from issue #465.

Changes:

• Documents that region accepts the region subtag from a listed locale code, with en-IN and fr-CA as examples.
• Notes that callers who already know the full locale code can use locales=[...] directly.

I looked into the failed Build run. The docs job had passed; the failure was limited to the Python 3.13 jobs running under Pacific/Auckland and Pacific/Fiji. Those jobs crossed a month boundary relative to UTC, so incomplete dates such as 2014 were using the parser's UTC day but the local CI month. That could produce an invalid intermediate date like June 31 and fall back to December 31.

I pushed a small follow-up commit to keep the current month and day on the same parser-relative base and added a regression test for that case. The new Actions runs are currently in action_required, so they need maintainer approval before they can execute.
