feat(popover): updating popover alignments

[andreancardona]

Closes #8873

This feature updates the alignments on Popover to be similar to that of tooltip / aligned to how a reader would view the popover placement

Testing

• Make sure all of the alignments follow visual flow ex: bottom the text box moves below the caret
• ex: right the popover moves all the way to the right of the screen

Is right and left supposed to be hanging off the page like that?

FYI @laurenmrice this change updates the align prop to make it easier to understand where the popover is relative to the trigger element.
