fix: [RTE] embed entries in correct place when using hotkeys

[MayaGillilan]

Removing selection in #1354 and #1353 introduced a regression specifically for users of hotkey insertion. Focusing improvements in those PRs are retained.

@MayaGillilanContentful Can we add a test that covers this please? So we don't remove it again in the future!

I thought about this, not sure if we can actually since we only have a mock slide-in on the field-editors testing which doesn't actually "exist" or trigger any of this sdk.navigator watching logic that Daniel implemented. Or do you have another idea on how we could test it?

If not, I can at least add a comment explaining why we need it

❓ Wouldn't a component/integration test work for that? 🤔

@MayaGillilanContentful if we don't add a test, can we add a comment explaining it above the code line? just making sure we know what it does in the future and we do not remove it again
