### Describe Your Changes
This PR is aimed to change the currently in place configuration of
running Go related jobs for code changes that don't contain actual Go
files ([example
1](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6517/checks)
- 2m32s , [example
2](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6543/checks)
- 4m11s).
In order to do that the `build` workflow was extracted from Go related
workflow (now it doesn't require lint as a `need` step -- let me know if
it's something we want to keep). It will run upon the same triggers as
before the change.
The `main` workflow now will be triggered by `**.go` pattern only and
contains lint/test steps that are relevant for Go file changes.
I expect this PR +
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6540 to improve
CI minutes usage.
