Added 'Submodule Compatibility Guide' link to dockerhub documentation

PR Details

Description

Problem

The dockerhub documentation for the project references submodules, but does not provide guidance on what versions of the submodules to use.

Solution

A link to the 'Submodule Compatibility Guide' has been added to the dockerhub documentation. This is currently linking to the CDOT fork, as the guide does not yet exist in the parent project. A local reference would have been used, but the dockerhub documentation is expected to be posted on the DockerHub page for the ODE image, so a direct link is more suited here.

Related Issue

No related GitHub issue.

Motivation and Context

Users who are reading the dockerhub documentation should be aware of the Submodule Compatibility Guide.

How Has This Been Tested?

Clicking on the link has been verified to properly redirect to the blob page on the dev branch of CDOT's fork.
