+- [scheduler] Remove dead CSS variable writes in `EventTimelinePremiumContent` (#22720) @rita-codes


Suggested change

- [scheduler] Remove dead CSS variable writes in `EventTimelinePremiumContent` (#22720) @rita-codes

- [scheduler] Remove dead CSS variable writes in `EventTimelinePremiumContent` (#22720) @rita-codes

- [scheduler] Show scope dialog when deleting a recurring event (#22552) @Anexus5919

I've bumped other scheduler packages too (except 2 headless ones). Is this correct?

Yesss, we had to change a small thing there, so that's expected (we updated the headless packages names, now we call them internals)

But the change should be under premium, because the recurring events are only available on premium, so
you will never see the scope dialog on the community version

The change we made on the community version is just a rename of the function that triggers the deletion (and decides if we show or not the scope dialog)

OK, moved it to premium
