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

[Quadrubo]

Describe the feature or enhancement

Description

As of the point of writing this, v2.13.2 is the latest Umami 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:

• v2.13.2 - Version 2.13.2
• v2.13.1 - Version 2.13.1
• latest - Version 2.13.2

Desired Behavior

I would propose a tag system like this:

• v2.13.2 - Version 2.13.2
• v2.13.1 - Version 2.13.1
• v2.13 - Version 2.13.2
• v2 - Version 2.13.2
• latest - Version 2.13.2

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 v2 and would have automatically gotten the update up to 2.13.2. However I won't get the update to a new major version like "v2.x" which would be desired for me.

This is all done in the GitHub workflow files. Would welcome a PR.
