Create Docker images of all old model tags

[dfsnow]

To improve model reproducibility, we should create Docker container images containing all the necessary dependencies to run all currently tagged versions of each model. This would involve building a Docker image of the specific R version used + building all the R dependencies captured in renv.lock.

These images should then be saved to each model's respective registry and tagged using the same git tag as the code, i.e. 2022-assessment-year.
