Description

As a developer I want to use @pinia/testing for testing pinia in unit tests to make sure sure my code is stable

Problem:
MW uses Pinia 2.0.16 on production. But the current @pinia/testing@0.1.7 requires a peer pinia@">=2.2.6".
Pinia 2.3.1 is latest.

Proposed solution:
Is it by any chance possible to periodically update Pinia ? 🍍

Thank you!

Should we configure LibUp to automatically upgrade extensions' test copies of pinia & @pinia/testing accordingly? I made 1303547 for WikiLambda but it could have been trivially done by a bot. Will other repos (pinia, @pinia/testing) be generally as trivial?

Yes, that would be helpful! Both pinia and @pinia/testing packages have little to no breaking changes, so it should be a straightforward upgrade. Although, I recommend pinning @pinia/testing to 1.0.3 instead of ^1.0.3 to align with MW core's package.json.
