github: add webhook formality check

Replace the external formality check GitHub Action with a lightweight
webhook managed by the openwrt-bot-worker engine.

Using a webhook instead of a heavy GitHub Action workflow is much more
suitable for quick formality checks. GitHub Actions are constrained by
concurrency limits across repositories, often causing long delays. In
contrast, the webhook validates commits near-instantly.

The validation rules are configured via .github/formalities.json. Since
verifying PKG_VERSION, PKG_RELEASE, and mandatory release notes are
not relevant for the LuCI repository (unlike packages), these checks are
disabled.

Additionally, the formality check is now a hard requirement. The build
workflow will only run once the formality check passes, saving runner
resources.

Requires:
#8757 - based on top of this branch
#8759
openwrt/actions-shared-workflows#126

Pull request overview

This PR replaces the repository’s GitHub Actions–based “formalities” check with an external webhook-driven FormalityCheck, and gates the build workflow on that check completing successfully to avoid wasting CI capacity.

Changes:

• Remove the formal.yml workflow that previously ran HyperStickler for commit/message formalities.
• Update build.yml to wait for the FormalityCheck / Git & Commits check-run before running the reusable multi-arch build workflow.
• Add .github/formalities.json to configure the webhook’s formality validation rules (disabling package-specific checks not relevant to LuCI).

Reviewed 2 new commits; one minor nit inline. Both commit messages match their diffs. The .github/formalities.json config aligns with the PR description (package-specific checks disabled), and check_openwrt_meta: ["PKG_MAINTAINER", "PKG_LICENSE"] matches existing LuCI practice (95/100 and 99/100 of luci-app-* Makefiles set those, respectively). Note: I could not verify the lewagon/wait-on-check-action@v1.8.0 tag or the reusable-workflow/webhook behavior from here — those depend on external repos (actions-shared-workflows PR #126, the openwrt-bot-worker check name FormalityCheck / Git & Commits) that aren't in scope for this review.

Reviewed 1 new commit; no new issues found. The only change since the previous review is the removal of a trailing blank line at the end of .github/workflows/build.yml; the commit message still matches its contents.
