[FEAT] Add docker tags for major/minor/patch versions

[Quadrubo]

Description

As of the point of writing this, v0.8.1 is the latest Scrutiny version.
As I'm manually updating my images and not using something like "latest", I have to change the image tag every new release. It would be nice if I wouldn't have to do that for patch releases (minor releases too).

Currently these tags are provided:

• v0.8.1 - Version 0.8.1
• v0.8.0 - Version 0.8.0
• v0.7.3 - Version 0.7.3
• latest - Version 0.8.1

Desired Behavior

I would propose a tag system like this:

• v0.8.1 - Version 0.8.1
• v0.8.0 - Version 0.8.0
• v0.8 - Version 0.8.1
• v0 - Version 0.8.1
• latest - Version 0.8.1

This would allow pinning to specific version and allows the user to choose which semver types they are okay with auto updating.
I for example would have pinned to v0 and would have automatically gotten the update up to 0.8.1.
However I won't get the update to a new major version like "v1.x" which would be desired for me.
