feat: update teatest v2 to use charm.land

[lrstanley]

Changes in this PR

• Updated teatest v2 to use charm.land & bubbletea 2.0.0-rc.1 from beta.3

• Updated snapshots, though not sure if there should be a change. Looks like the core of the snapshots is still correct, but rendering adds a few new characters around the resulting text, I assume due to how bubbletea v2s new renderer does this.

• I have read CONTRIBUTING.md.

• I have created a discussion that was approved by a maintainer (for new features).

Looks like tests are failing on Windows due to \r line endings being added, I suspect something windows-terminal-specific. With teatest, and the new tea.View being used, which seems to render more raw terminal sequences than before, what's the best way to resolve this?
