Update dockerfiles

[billingsley-john]

Proposed changes

PR which re-organises the docker build which occur on PRs.

On push/PR to develop:

• ukaea/paramak:dev image is built which includes all paramak dependencies + paramak code on develop branch
• ukaea/paramak:dependencies image is built which includes all paramak dependencies
• ukaea/paramak:geometry-dependencies image is built which includes all paramak dependencies (excluding neutronics)

On push/PR to main:

• ukaea/paramak:stable image is built which includes all paramak dependencies + paramak code on main branch
• ukaea/paramak:dependencies image is built which includes all paramak dependencies
• ukaea/paramak:geometry-dependencies image is built which includes all paramak dependencies (excluding neutronics)

I.e. ukaea/paramak:dependencies and geometry-dependencies are built on both PRs to develop and main, so the image will be up-to-date with the most up-to-date of those branches.

All images build CQ2.1 which introduces stability into the paramak; however, this can be changed easily.
