update-readme.yml

# Update README.md (v4)
#
# Previous (v3): ran on every push to main regardless of whether composer.lock
# changed, and wget'd update-readme.sh from the v3 branch at run time.
#
# Next (v4): the script is bundled in the update-readme composite action.
# Callers should gate this workflow on composer.lock actually changing, e.g.:
#   if: contains(toJSON(github.event.commits.*.modified), 'composer.lock')
