PublishDate does not roll-up to section, taxonomy, or term pages about hugo

The version string was added to the generator tag in v0.125.0 to address #11692, and was removed in v0.125.3 to address #12300 (comment). We should have closed #11692 as "won't fix".

I'll look into the zero pubdate problem.

The Date and Lastmod roll-up to section, taxonomy, and term pages. The PublishDate does not "roll-up".

I think the PublishDate should roll-up to the latest date before now(). If we rolled-up dates after now(), that would cause the section, taxonomy, or term page to not be published even if there's other descendant content.

Applicable to:

• Automatic section, taxonomy, and term pages
• Section, taxonomy, and term pages without Date and PublishDate

This isn't something new (i.e., same behavior in v0.122.0).

The test case below does not test for what should happen with publish dates greater than now() as described above.

Failing test

I think the PublishDate should roll-up to the latest date before now().

Yea, that sounds reasonable.
