[feat] Add dependency updating bot and script for our dockerfiles

Is your feature request related to a problem? Please describe.
Everytime we update an ostk repo and do a release we have to manually propagate that up the chain

Describe the solution you'd like
We have already installed dependabot for the pip package manager, but that doesn't update our dependencies listed in the dockerfiles. So we should

1. Centralize all the versions of all our dependencies in a versions.env file at the root level
2. Create a github action that can go and modify the dependencies in our dockerfile every so often and open a PR if they need to be updated
