Replace ActionToast usage in RemoteTabsTableViewController with ButtonToast.

[lmarceau]

📄 Context

We have different Toast classes in the app. One of those is ActionToast which is only used in two places in the application at the moment. ActionToast is very similar to ButtonToast, so we should be able to replace ActionToast usage with the ButtonToast class. With recent changes to Toast, having extra classes to support makes it harder to make changes and have a unified design. Let's remove ActionToast while its not used in many places.

✏ Requirements

1. Replace ActionToast usage in RemoteTabsTableViewController with ButtonToast.
2. If there's some blockers/reasons why ButtonToast cannot be used there, please let us know in comments.
3. Put screenshots of before/after in your PR in light and dark mode.

Note: If ActionToast is not used anywhere else anymore, you can remove that class from the codebase.
