Closes #17274

This PR updates the Tab component to scroll programmatically selected tabs into view, regardless of tab activation type

Prior to this PR, Tabs in manual activation mode would only scroll when the active tab changed. Normally this is not an issue but when the selected tab is modified programmatically, the lack of user interaction means the selection does not occur on the active tab.

By splitting the existing useIsomorphicEffect into two separate hooks, they can handle manual and auto activation modes separately. This ensures that the component will scroll as needed both when changing the selected tab and when changing the active tab in manual `activation mode

Changelog

New

• scrollTabIntoView Tab method

Changed

• split existing useIsomorphicEffect that handled scrolling into two distinct useIsomorphicEffects for each activation mode

Testing / Reviewing

• visit the temporary Test Tabs story
• confirm that both activation modes will scroll the correct tabs into view as needed
