Remove `master` dependency overrides from craft config

## Summary

Back before the KF6 release, I set the craft.ini file to explicitly require master versions of some dependencies which did not have appropriate versions available. (!631)

Now that those are released, we should remove those overrides (also because they break the build!)

## Test Plan

Tested the pipeline on a private branch: https://invent.kde.org/network/kdeconnect-kde/-/pipelines/621529

Given this is passing, I plan to check in this change without waiting for another pipeline run.


(cherry picked from commit 11176224)

97920631 Remove `master` dependency overrides now that KF6 is released and those dependencies consume KF6.
