Show the version for Helm.

This will print a representation the version of Helm.

The output will look something like this:

- Version 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.
