Since otel removed functions and APIs in the otelgrpc 0.60.0 => 0.61.0 upgrade, it's now impossible for us to upgrade otel without also upgrading all of the kube dependencies.

So we cannot patch the otel (!) vulnerability in the 0.4 release of the syncagent. All users will sadly have to upgrade to 0.5.

Semver, what's that?

Cannot re-open this, but opened a new attempt to fix this in #145.
