Update workflow to add versioned image tags

[rafaelgaspar]

:recycle: Current situation

Currently the docker images are only tagged as latest and latest-ubuntu

That is not ideal for many reasons:

• Always overwrite the image, so in case of broken release the working release is lost
• Makes it to check for new versions in order to implement auto-updating mechanisms

:bulb: Proposed solution

This PR add the date in a sortable format(2023-12-31) as the image tag if it's the main(latest) branch or suffix the date to the branch name.

Fixes #531.

:gear: Release Notes

• Add versioned image tags with the current date in the format 2023-12-31.
