Add docker tags for major/minor/patch versions

[Quadrubo]

Description

As of the point of writing this, v1.4.3 is the latest node-hp-scan-to version.
I'd like to manually update my images and not use something like "latest".

Currently these tags are provided:

• latest - Version 1.4.3

Desired Behavior

I would propose a tag system like this:

• v1.4.3 - Version 1.4.3
• v1.4.2 - Version 1.4.2
• v1.4 - Version 1.4.3
• v1 - Version 1.4.3
• latest - Version 1.4.3

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 v1 and would have automatically gotten the update to v1.4.3 while not getting updates to v2.x which would be desired for me.
