Update WebSearch to version 1.10.18.
This includes recent WebSearch fixes and updates from the standalone repository.

WebSearch v1.10.18 includes the following updates:

1. Support multiple UID attribute values (Support multiple UID attribute values jurchello/WebSearch#140)
   WebSearch can now show multiple links when the same UID attribute exists more than once for the same service.
2. Fix saved link row mismatch after DB refresh (Fix saved link row mismatch after DB refresh jurchello/WebSearch#141)
   Fixed a row tracking issue where saving a selected link could save a different link after the WebSearch list refreshed.
3. Add database scoping to local WebSearch records (Add database scoping to local WebSearch records jurchello/WebSearch#142)
   New local WebSearch records now include database identity metadata so saved, visited, hidden, and activity data can be scoped more safely
   across different Gramps trees.
4. Hide selected links by exact final URL (Hide selected links by exact final URL jurchello/WebSearch#143)
   Hiding a selected generated link now uses the exact final URL, so duplicate templates that produce different links are handled correctly.
5. Check the RootsSearch WikiTree addon tool (Check the RootsSearch WikiTree addon tool jurchello/WebSearch#138)
   Added RootsSearch WikiTree support for profiles with a WikiTree ID.
6. Autorefresh doesn't work for grouped people and ungrouped places (Autorefresh doesn't work for grouped people and ungrouped places jurchello/WebSearch#118)
   Fixed refresh behavior when Gramps views do not provide a concrete active person or place item.
7. Notification that a Note was generated is unreadably dim (notification that a Note was generated is unreadably dim jurchello/WebSearch#117)
   Improved WebSearch notification readability by increasing contrast and adjusting the notification size.
8. Add context menu item to open the Attribute, Note, or Internet object reference object
   (Add context menu item to open the Attribute, Note, or Internet object reference object jurchello/WebSearch#116)
   Added context menu actions to open and edit the original Gramps item that contains a WebSearch result link, including supported Attribute,
   Note, and Internet link records.

When a new translation is available, the version gets bumped. This will make your tracking by version numbers impractical.

I am merging the Weblate PR that includes many translations that affect WebSearch. So the new release will bump the version on the 6.1 branch.
