Subject: Wrap prometheus/sigv4 package

Forwarded: not-needed
Last-Update: 2025-02-16

Some downstream dependencies still import prometheus/common/sigv4, which
has been moved by upstream into its own repo (github.com/prometheus/sigv4)
and is packaged separately as golang-github-prometheus-sigv4. This patch
provides a type alias / thin wrapper for backwards compatibility.
