consider parameterizing base image name/tag

https://github.com/RMI-PACTA/workflow.prepare.pacta.indices/blob/dd1e27d74ba8b24a9eedf744ef9553436c47f257/Dockerfile#L10C69-L10C77

ARG BASE_IMAGE=transitionmonitordockerregistry.azurecr.io/rmi_pacta:2021q4_1.0.0

The base image for the Dockerfile is hardcoded to rmi_pacta:2021q4_1.0.0, but the image to be used is probably dependent on which quarter benchmark data is being generated for, so it would be advantageous if the image name and/or tag were parameterized.

Note: We could also consider using the auto built images on GHCR from workflow.transition.monitor as the base image since we're requiring loading in a local PACTA data set here.
