Bumps metcalfc/changelog-generator from 4.7.0 to 4.8.0.

Sourced from metcalfc/changelog-generator's releases.

Release v4.8.0

Highlights

Failed changelog generation now fails the step

If the changelog could not be generated — an unresolvable ref, any git error — the action printed an ::error:: annotation and then exited 0. The step went green, outputs.changelog was never set, and downstream steps consumed an empty string without anything indicating a problem.

It now exits non-zero.

[!WARNING] This is a behavior change. A workflow that was quietly passing on a broken changelog will now fail. That is the point — but expect it to surface as new red builds rather than as new errors, since the errors were always being printed.

fetch: true no longer intermittently fails on shallow checkouts

The default fetch path chained two git fetch --depth=1 calls ahead of git fetch --unshallow. Each rewrites .git/shallow while the next has already read it, so git would intermittently abort with:

fatal: shallow file has changed since we read it

Because fetch: true is the default and the exit code was being discarded, this produced a silently empty changelog rather than a visible failure. It was happening in this repository's own CI.

Now a single fetch, requesting --unshallow only when the checkout is actually shallow.

Testing

make test previously ran npm test || echo "no tests available", where npm test was exit 1 — it reported success unconditionally. The project now has a real suite covering changelog.sh against live git fixtures, ref validation, the release scripts, and the built dist/ bundle as the runner executes it. Both fixes above were found by adding it.
