Add option to ignore dependency checks

[goggle]

I run addon-check via Github actions in my plugins Github repositories. When I update the required versions for my dependencies and they are not published yet (in the official Kodi repository), it always fails with this kind of error message:

ERROR: Version mismatch for required dependency script.module.xyz, required: 2.2.3, Available: 2.2.2

So it would be nice to have an option to ignore dependency checks (at least for my use-case).
