Description of Problem

• See image updater github issue https://github.com/argoproj-labs/argocd-image-updater/issues/1445
• After the image-updater runs for some time, git operations fail with errors like:

error: cannot fork() for remote-https: Resource temporarily unavailable
error: RPC failed; HTTP 500 curl 22 The requested URL returned error: 500\nfatal: expected flush after ref listing

Observed inside the container there are 8,141 git processes, and further git commands fail with exit status 255 or 128. This appears to be either process/fork() exhaustion or leaking/unreaped git helper processes.
