fix(release): correct mislav/bump-homebrew-formula-action inputs
The v3 action's input is `homebrew-tap`, not `tap`, and it wants the
tap repository name (e.g. `dunglas/homebrew-frankenphp`) rather than
the brew tap shorthand. The unknown `tap` input was silently ignored,
so the action defaulted to `Homebrew/homebrew-core` and the v1.12.3
dispatch failed with HTTP 403 trying to push there.
