Introduce image version

[randomir]

Currently, ocean-dev tags contain up to 3 components, listed in the following order

• Ocean version (number like 6 or 6.9)
• Python version (string like python3.11)
• Platform (bullseye/windowsservercore)

To enable independent versioning of image (e.g. environment) changes unrelated to Ocean/Python/platform, we have to introduce the fourth version, probably as a prefix. In addition, we may want to add ocean prefix to ocean version tag components.

For example: 1.2-ocean6.9-python3.12-bullseye. Or 1-6.9 without the ocean prefix`.
