[RominaMarchetti]

What does this PR change?

This PR updates the interaction tooltip mouse icons and the copy when hovering another avatar.

Test Steps

1. Launch the explorer.
2. Hover an interactive object in the 3D environment to validate the icon has the new look and field.
3. Hover an avatar to validate the icon has the new look and field and the wording is now 'Options' instead of 'Interact'.
