[Pharo6] Failing tests on CI: 6

Hi,

We have 6 tests failing on the CI:

SmalllintManifestCheckerTest.testCriticsOf
SmalllintManifestCheckerTest.testToDoOf
        - tests need to be updated, will be fixed with next QA update

ReleaseTest.testLocalMethodsOfTheClassShouldNotBeRepeatedInItsTraits
        - fixed upstream

SystemAnnouncerLiveTest.testNoDeadSubscriptions
Announcements.Tests.Core.Tests.WeakAnnouncerTest.testNoDeadWeakSubscriptions

ClassDescriptionTest.testClassDescriptionRespectsPolymorphismWithTraitDescription
        #iconNamed: in ClassDescription.


Any help to get this number down is welcome!
