Correction for German translation: "durchsucht" instead of "gesucht"

In mintinstall (tested in version 8.4.0), the string "Searching package sources" is translated as "Paketquellen werden gesucht". This appears specifically when a user enters a search term in the search bar.

There are two issues with the current translation:

Contextual: At this stage, the application is not searching for "sources" (repositories), but for applications/packages within the already indexed data. Using "Paketquellen" is technically misleading for the user.

Semantic: In German, "gesucht" implies searching for something lost or unknown (searching for). Since the app is scanning known data, it should be "durchsucht" (searching through / scanning).

Proposed Solution: I suggest changing the string to something more accurate for the search process:

Preferred (German): "Suche läuft – einen Moment bitte" (Search in progress)

Alternative (German): "Paketquellen werden durchsucht – einen Moment bitte" (Scanning package sources)

The first option is more user-friendly as it describes the actual action the user just triggered.

No file or test is named. Search the mintinstall translation resources for the string "Searching package sources" and inspect how its German text appears in the search bar. Done means updating the German wording to the agreed alternative and verifying it is shown during a package search.
