Show correct exporter version

[Dmitry-Eremeev]

#64

[Knalltuete5000]

From my testing with your patch there no version displayed either by running

./prometheus-libvirt-exporter --version
libvirt_exporter, version  (branch: , revision: b2cead90be5d2455a2a5a75c1aa719f241b82993)
  build user:       
  build date:       
  go version:       go1.23.5
  platform:         linux/amd64
  tags:             unknown

or when starting the exporter

level=INFO source=main.go:47 msg="Starting libvirt_exporter" version="(version=, branch=, revision=b2cead90be5d2455a2a5a75c1aa719f241b82993-modified)"

Have you received other results?

Hi,

you don't see version because there is no version in your binary.
Please do git commit and add git tag.
Build your code by goreleaser.
Or you can take release code and build it:
https://github.com/inovex/prometheus-libvirt-exporter/tree/v1.6.0

I have tested the current main branch and your changes with the goreleaser and can confirm the change works as expected. Thanks for the contribution and the fix
