Relabel geospatial and advanced search accordion menus

Why these changes are being introduced:

The change in label for these accordions when open (e.g.,
'Advanced search' to 'Close advanced search') is unnecessary and
confused some usability test participants.

The 'Advanced search' menu was also unused without prompting
in usuability testing. UXWS has suggested relabeling it for
clarity.

Relevant ticket(s):

* [GDT-301](https://mitlibraries.atlassian.net/browse/GDT-301)

How this addresses that need:

This relabels the accordion menus as suggested by UXWS.

Side effects of this change:

None.
