docs/changelog: add link to issue

The `Version` panel shows an empty value when a service is built from a
feature branch. In such cases, `short_version` label is not available,
so `by(job, short_version)` grouping produces no visible value in the
panel.

Previously, to see the actual version, one had to manually edit the
panel query and add the relevant `version` label to the `by()` clause.

The fix tries `short_version` and when empty falls back to a long
`version` label.

This is applied uniformly across all dashboards:
- victoriametrics (single-node)
- victoriametrics-cluster
- vmagent
- vmalert
- vmauth
- operator

PR simplifies debugging with custom or feature-branch builds.
