Bug description

Description:

The kluctl-controller fails with the following error when trying to clone a Git source from a GitLab repository that uses the sha256 hash algorithm:

failed to clone git source: pkt-line 1: no space after hash (370407d7534af945a348385e HEADmulti_ack thin-pack side-band side-band-64k ofs-delta shallow deepen-since deepen-not deepen-relative no-progress include-tag multi_ack_detailed allow-tip-sha1-in-want allow-reachable-sha1-in-want symref=HEAD
/heads/main filter object-format=sha256 agent=git/2.46.2)

Additionally, kluctl throws the following error when attempting to interact with the same repository using diff, deploy, or prune commands:

packfile not found

Steps to reproduce

git init --object-format=sha256 k8s-deployment-test

and use it for a kluctl deployment

or (what I did by accident)

Relevant log output

No response
