Show the version for Helm.
This will print a representation the version of Helm.
The output will look something like this:
Client: &version.Version{SemVer:"v2.0.0", GitCommit:"ff52399e51bb880526e9cd0ed8386f6433b74da1", GitTreeState:"clean"}
- SemVer is the semantic version of the release.
- GitCommit is the SHA for the commit that this version was built from.
- GitTreeState is "clean" if there are no local code changes when this binary was
built, and "dirty" if the binary was built from locally modified code.
