Update dotnet-ef to roll forward across major .NET Core versions

[bricelam]

This should unblock dotnet/aspnetcore#17947

Hmm, no validation build got kicked off. I suspect the org change busted our AzDO integration. This is important here because I wanted to double-check the created package ☹️

@mmitche @Pilchie @wtgodbe @JunTaoLuo @anurse what needs to happen to get our pipelines running again? Is it just renaming the pipelines too?

[mmitche]

/azp run

[azure-pipelines]

Azure Pipelines successfully started running 1 pipeline(s).

[dougbu]

Thanks @mmitche❕

[dougbu]

Things got very confused as pipelines were renamed. Closing and reopening…

[JunTaoLuo]

@BrennanConroy and @Pilchie just updated the pipelines so builds should be triggering now.

[dougbu]

Thanks for doing that work @BrennanConroy❕

[dougbu]

BTW I'll sign off once I see the added tag in action i.e. once the validation builds produce artifacts.

[dougbu]

Shoot. I forgot we don't create package artifacts for PR builds of forks. @bricelam I suggest checking this in and checking the next official build to make sure this works as expected.
