Cannot search for items in Unity settings pages

Unity settings pages do not show up when entering keywords which are used on the pages themselves into settings' search field.

Turns out this is CI configuration. Main TeamCity configuration is not specifying Release mode correctly. This means we don't create and bundle the searchable options index, and we're also building and distributing the Debug build of the .net assemblies 🙀 ~

UPDATE: We're not building the .net assemblies in Debug mode. We override the build configuration in the scripts when we discover that we're running under CI.
