[Meta] Release Plan for AP Style Date Patch/Bugfix Release 2.1.1 [#3557521]

Problem/Motivation

The intent of this issue is to coordinate efforts in the creation of the 2.1.1 release of the AP Style Date module.

This release adds a bugfix introduced in the 2.1.x release branch.

Bugfixes cherry-picked from 3.0.x

#3556754: Declaration of Script Types causes type error in FieldFormatter

Because we cherrypicked the fix for #3556754 we brought in some syntax that we later removed with a follow-up commit.

Remaining tasks

~~Finalize and review all release-blocker issues~~
~~Ensure automated tests pass on Drupal 10.3 and Drupal 11~~
Tag 2.1.1 release

Draft Release Notes

<p>Fixes a type error in FieldFormatter caused by strict type declarations. The fix was cherry-picked from 3.0.x and required compatibility adjustments for the 2.1.x branch due to DateTimeRangeTrait usage.</p>
