Apparently ther are problem with the proposed fix for Pharo 13. But now the Pharo 12 and 11 should work.
@SullyMLT Do you have other ideas to fix Pharo13 CI?

The bug is:
Instance of SpTextInputFieldPresenter did not understand #ensureActionGroup
See: https://github.com/OpenSmock/Pyramid/actions/runs/16627861494/job/47049188471?pr=225

[SullyMLT]

@Nyan11 I change the ensureInternalActions and put it like it was before natively in pharo 13

[SullyMLT]

Don't run test in Pharo 13, the class PyramidSaveModelVerifier rewrite the message methodIsValid
Original :

^ self new
	  verifyBlock: [ :model |
		  model savingMethodName isValidSelector ];
	  showBlock: [ :view | view showMethodIsNotValidError ];
	  yourself

to :

^ self new
	  verifyBlock: [ :model |
		  OCScanner isSelector: model savingMethodName ];
	  showBlock: [ :view | view showMethodIsNotValidError ];
	  yourself

The problem is if we run it and commit push the methodIsValid is pushed with the rewrite version on github so we don't run at local before and the Pharo 12 CI used it and don't pass the test
