Mark bump-prs commits/titles #none so they don't fire releases (#851)

Bump PRs target master, where auto-tag.yml mints a tag and triggers
release.yml on every push. A pin edit is a deploy gesture, not a release,
so each merged bump was minting a spurious release. Add #none (honored by
anothrNick/github-tag-action) to both the commit message and the PR title
so the skip-tag marker survives whether the PR is merge-committed or
squash-merged.
