Themes: Replace "Active" wording with "Installed" in the theme install checks page.

When reinstalling a theme by uploading a ZIP file, the wording used in some strings referred to the "active" theme even though it's not the currrently active theme. This changeset replaces these strings to refer to the "installed" theme, which is more accurate.

Follow-up to [52610], [52580].
