[CHORE]: Make geo traces use fitBounds by default #7885

Description

Update geo traces to use fitbounds: 'locations' by default instead of false.

Why should this change be made?

It's better UX to zoom in to what data the user passes in for map based plots.

Scope

• Change the default for fitbounds to 'locations' and update any baseline images that change as a result
• Look for any unintended changes after this update
• Fix any bugs that show up as a result of the update
