fix: quickstart demos

[SkypLabs]

Hi there,

I started to play with your quickstart examples and I realised that the Kratos configuration files are targeting very old versions of the tool (e.g. v0.7.1-alpha.1), which make them invalid according to your current configuration JSON schema.

This PR upgrades the version numbers in the Kratos configuration files located in contrib/quickstart. I also took the liberty to upgrade the Docker image of Oathkeeper in quickstart-oathkeeper.yml.

The Oathkeeper quickstart demo is partially broken as the /sessions path is not part of access rules despite the presence of a link to the "Session Information" page on the Dashboard:

Would you like me to fix it in this PR as well? If so, I could rename it to "fix: quickstart demos" or similar.

That would be awesome! :)

I removed the unused routes (/debug and /dashboard) and added the missing ones (/sessions, /health/alive and /health/ready).

I also rebased my branch onto master.
