fix: wrong version logged on startup

[apricote]

The k/cloud-provider library is logging a version on startup. This version is expected to be set by Kubernetes build scripts, but we do not use this.

Right now it looks like this:

controllermanager.go:169] Version: v0.0.0-master+$Format:%H$

With the fix, this will report the same version as we use for the user-agent.

Should we maybe add some more details ?

I am against that, build information is automatically added through https://pkg.go.dev/runtime/debug#ReadBuildInfo.

I only patch this field because its being logged by a component outside of our control.
