commit 676d9d220a8a71f207701fc8568078028235aea6
Author: Jan Schär <jan@monogon.tech>
Date:   Wed Apr 30 09:30:04 2025 +0000

    Add stampsrcs attribute
    
    This change adds the stampsrcs attribute, which allows providing a list
    of files containing variable definitions, which are used in addition to
    the stable and volatile status files and have the same format.
    
    See https://github.com/bazel-contrib/rules_go/issues/3507
