name: Label PR version

|
# Contributors (especially from forks) can't set labels themselves — that needs
|
|
# triage rights. A PR's version line is fully determined by its base branch, so
|
|
# this reads base.ref and applies v1/v2 on their behalf. pull_request_target runs
|
|
# in the base repo's context so it has write access even for fork PRs; it only
|
|
# reads trusted metadata (the base ref) and never checks out or runs PR code.
