[web] Remove usage of setTab and replace with setCurrentTabType
Summary:
Remove setTab since it's no longer necessary and replace usages with setCurrentTabType which does the exact same thing.
As part of the work to refactor ThreadSettingsModal... specifically to turn it into a functional component.
Depends on D3763
Test Plan:
- Open ThreadSettingsModal
- Switch between tabs as before
