Newer branches are not used

Example: Polish, 3.14 is now default

[rffontenelle]

Brazilian Portuguese has a "3.14" branch which is not the default branch ("main" is), and 3.13 is being shown too.

The versions list is based on devguide's releases JSON. It lacks beta releases date information.

I've opened python/devguide#1554, but it probably will wait for python/peps#4331.

I wouldn't be opposed to reuse code from Transifex automations repo to get the beta date though.

Alternative solution: allow prerelease in branches_from_devguide() as a workaround. Then we should apply a better solution or revert between 3.14 becomes bugfix version (2025-10-07) and 3.15 is a new prerelease (2025-10-14).

I incorrectly assumed that prerelease status is not a synonym of beta (a.k.a. feature freeze). It occurs that fix wasn't a workaround, but a correct and final fix. Please compare:

• 3.14.0 beta 1 released on 2025-05-07, feature status changed to prerelease that day
