Issue #22: Upgrade to PHP 8 (#23)

- Upgrade to PHP 8. Uplift dependencies to latest versions.
- Remove reference to my fork of `guzzle-services`. Guessing I had a patch in there that wasn't at the time merged. Seems like everything is working now.
- PHPUnit nicely migrated the configuration file to its new format.
- Drop PHP 7 from test matrix. Only PHP 8 versions now.
