feat(ci): allow explicit docker_tag from workflow dispatch in docker-… (#322)

…tag action

Introduce an `docker_tag` input to the `docker-tag` action. This allows
overriding the tag generation logic for workflow dispatches by providing
an explicit tag.

This change updates the action to accept an optional `docker_tag` input.
It is then used to skip prefixing the tag if provided, enabling users to
specify the exact tag when manually triggering a workflow. The new input
is passed to all relevant build workflows.

chore(ci): pass docker_tag input to build/push workflows

Propagate the `docker_tag` input to the `build` job step within multiple
CI workflows. This ensures that the provided tag is correctly used when
building and pushing images, maintaining consistency across different
upstream repositories being built.
