Its `paths` filter listed `i18n/**` but not the workflow file, so a change to the
workflow - an action bump, say - triggered nothing. Those bumps automerge on a
branch, so they were merging with nothing having run them.

The Molecule workflow already lists itself for this reason. `update-translations.yml`
cannot do the same: it only runs on pushes to master, and it holds `contents: write`
and `pull-requests: write` to open translation PRs, so running it from a dependency
branch would be worse than not exercising it. Its bumps stay unexercised on purpose,
and a broken one shows up as a failed translations run rather than as anything users
see.

molecule-shared/ and the workflow itself are used by every scenario, so a
change to either has to run all of them rather than only the roles whose own
files moved. They were also missing from the paths filter, so such a change
would not have triggered the workflow at all.
