Align Geo Settings Page Width

What does this MR do?

Closes #215344 (closed)

Currently the Geo Settings page has a limited width on Fixed Layout.

The other Geo pages do not do this, so this page ends up looking a lot different than its sibling views.

This MR removes the restriction on fixed and lets the page have the same width as the other Geo Pages.
