Rahul Vats e0e3454998 Add v3-4-test to CI, dependabot, backport, and fork-sync configuration (#74219)
The v3-4-test release branch was cut for the 3.4.0 release cycle, so the
automation on main needs to track it (switching off the now-retired v3-3-test):

- dependabot.yml: switch release-branch dependency updates to v3-4-test
- milestone-tag-assistant.yml: add v3-4-test to the push-branches list
- ci-notification.yml: switch the workflow-status matrix branch to v3-4-test
- boring-cyborg.yml: move the dev-tools backport auto-label rule to v3-4-test
- dev/sync_fork.sh: switch DEFAULT_BRANCHES to v3-4-test
- scheduled-upgrade-check: rename the per-branch workflow to v3-4-test

# Sync branches on your fork with the upstream Apache Airflow repository.
#
# Force-pushes the named branches from <upstream>/<branch> directly to
# <origin>/<branch>. Does not touch your local working tree or checked-out
# branch.
#
# WARNING: this OVERWRITES the listed branches on your fork. Any commits you
# have on those branches in your fork that are not in upstream will be lost.
#
# Usage:
# dev/sync_fork.sh [branch ...]
#
# Examples:
# dev/sync_fork.sh # sync the default branches
# dev/sync_fork.sh main # sync only main
# dev/sync_fork.sh main v3-2-test v3-1-test # sync several branches
#
# The upstream and origin remote names default to "upstream" and "origin" and
# can be overridden via the UPSTREAM_REMOTE and ORIGIN_REMOTE env vars.
#
# NOTE FOR RELEASE MANAGERS: when a new vX-Y-test branch is cut, update the
# DEFAULT_BRANCHES list below to include it (and drop branches that are no
# longer maintained).
