version=0.0.0 in logs when running v1.5.1 from Docker image

[rc5hack]

I upgraded from v1.3.0 to v1.5.1, using Docker image:

# old one
nginx/nginx-prometheus-exporter:1.3.0

#new one
nginx/nginx-prometheus-exporter:1.5.1

When running v1.5.1, the first line in log is

time=2025-10-23T04:53:33.971Z level=INFO source=exporter.go:126 msg=nginx-prometheus-exporter version="(version=0.0.0-SNAPSHOT-bae43bc, branch=main, revision=bae43bc818cd6e47a08163a7b31f355f454e9ecb)"

When running older v1.3.0, the first line in log is

ts=2025-07-28T01:08:36.828Z caller=exporter.go:124 level=info msg="Starting nginx-prometheus-exporter" version="(version=1.3.0, branch=HEAD, revision=9522f4e39ee1aed817d7d70a89514ccc0ae1594a)"

Seems like a builder issue, which prevents builder from knowing actual version on docker iamge build.

This problem does not reproduce on the previous v1.5.0:

time=2025-10-23T04:59:54.127Z level=INFO source=exporter.go:126 msg=nginx-prometheus-exporter version="(version=1.5.0, branch=HEAD, revision=b14979c9f3634dcd5a2b158874e713beb3aca3d7)"
