Geo - Update Verification Popover

What does this MR do?

Closes #209262 (closed)

There is currently an overall effort of making the Geo Admin screen more intuitive.

This MR focuses on the Geo Node Verification Information. We have gotten feedback that the information is repetitive on every verification item. Instead we decided to move the popover information to the tab itself, and thus require to only have one popover for all verification information on each node.

How:

• Remove old legacy code for popover
• Remove props that passed down popover info to each sync item
• Use GlPopover on the Verification Tab itself
