Update composer.json for Laravel 9

Hope this helps - composer packages updated - lets see if CI tests pass too

@mpociot - I think this is ok, it would be great if you could check and merge if ok. Even if you don't tag a release we could still pull it in using dev:master and run our Laravel 9 upgrades :)

I agree with @colinmackinlay. Ideally this package needs to cleaned up to remove support for old versions. But meanwhile if @mpociot can get at least merge this PR we could use it with Laravel 9. That's the only package preventing me from upgrading.

I just did a yolo merge into dev:master based on your comments and put this on our list if packages that need more love soon! Without further testing, I don't want to tag a new release today.

Thank you - that seems very sensible. We can now choose to require dev:master at our own risk. If we encounter any issues I'll report back, maybe even with a PR to fix :)
