* Replace 8.1-deprecated utf8_ funcs with mbstring (#326)

* Treat PHP version numbers as strings in GitHub Actions (#327)

YAML will try to interpret numeric values as numbers, leading to `8.0` being
interpreted as `8` instead of `'8.0'`.

This doesn't result in a functional change, but cleans up the output of the
jobs a little (e.g. in the title line).

* Update to `actions/checkout@v3` (#328)

This does not introduce any functional difference and is intended as a
future-proofing change.
