Bug 2386530

External tools like helmfile may rely on `helm version --short` output.

Current Fedora helm packaging uses raw version (i.e. 3.18.4+gd80839c) while https://github.com/helm/helm provides v-prefixed version (v3.18.4+gd80839c).

With helmfile 1.1.3 (helmfile is a popular wrapper for helm tool), this not-prefixed version trigger an errror :

```
$ helmfile diff
panic: error find helm srmver version '3.18.4+gd80839c
	': unable to find semver info in 3.18.4+gd80839c


goroutine 24 [running]:

```

This helmfile issue was opened : https://github.com/helmfile/helmfile/issues/2107. I think Fedora package behavior is not new, but helmfile recently updates its helm version extraction, so it triggers the issue.

Even if helmfile may relax version check, I think Fedora packaging should follow official helm binary behavior, and uses a v-prefixed version.

From my package build understanding, helm.spec should be modified to use `helm.sh/helm/v3/internal/version.version=v%{version}` (v added before `%(version)`).

Reproducible: Always

Steps to Reproduce:
Install helm from Fedora package.

Install helmfile 1.1.3 (https://github.com/helmfile/helmfile/releases/tag/v1.1.3)

Run `helmfile diff` from a helmfile folder.
Actual Results:
```
$ helmfile diff
panic: error find helm srmver version '3.18.4+gd80839c
	': unable to find semver info in 3.18.4+gd80839c

Expected Results:
diff is performed.
