fix(scripts): pass docker_socket variable to tasks-docker template

bpmct · bpmct · commit c5f9e309cea7 · 2025-12-10T15:16:21.000Z
The DOCKER_HOST variable was being set but not passed to the template.
This commit:
- Creates params.yaml with docker_socket parameter
- Passes params.yaml via --variables-file flag to both template pushes
- Adds docker_socket variable to tasks-docker template matching docker template pattern

This ensures the template can connect to non-default Docker sockets when needed.
