Georgi Gerganovci : add nightly-tag.txt to make-release (#27485)e467c2ff62026-08-21

#!/bin/bash
# Generate the description of a release: the previous release version, the
# change log and the link to the nightly release corresponding to the commit being released.
#
# Usage: make-release-desc.sh <version>
#   <version>: current release version (v<maj>.<min>.<pat>, the leading v is optional)
#
# The previous version is the highest plain semver tag (v<maj>.<min>.<pat>)
# strictly below <version>. The change log lists all commits between the
# previous version tag and the release commit, one line per commit.
#
# The release commit is the commit <version> points at when the tag exists,
# HEAD otherwise. The nightly release is the b* tag pointing at that commit
# (release.yml tags the same commit); the link is only generated when that
# tag exists.
#
# Env (when running in GitHub Actions):
#   GITHUB_OUTPUT: previous_tag, changelog_title, changelog, nightly and nightly_tag
#     are written here
#   GITHUB_REPOSITORY: owner/repo, used to build the nightly release URL (skipped when unset)
