Upgrade to bubbletea v2.

[theantichris]

Bubbletea v2 is out. We should upgrade.

[NucleoFusion]

We could, but we need to ensure that the bubbles/ other components we use also migrated to v2

[theantichris]

Yeah, I've already updated my big project to v2 a few weeks ago and it wasn't too bad. I need to look at the overlay dependency in Toney though.
