Default cipher values are invalid for newer versions of go.

[joshrwolf]

This is not a bug with a current release, and I'm happy for it to be reclassified as such!

This is simply a proposed (hopefully simple) fix for a future problem that will arise when the project upgrades the version of go used to build.

Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Is the fix for this is any argocd version yet? @alexmt

We upgraded to Argocd v2.12.3 from v2.11.1 and are seeing this same error in logs for the argocd-server and argocd-repo-server. Both the pods are currently stuck in a CrashLoopBackOff state unable to start up successfully? Is there a workaround for fixing this? @alexmt If not to which version can we downgrade to resolve this?
