Create workflow to ensure all tags have an associated docker image for Compatibility testing.

[chatton]

Summary

Occasionally, errors occur during release workflows, or workflows that are designed to build docker images based on release tags (for use with compatibility tests)

Compatibility tests can be time consuming, so finding out that an image does not exist only when running tests will slow down the release process.

We should add a workflow that will ensure images are built for all released ibc-go versions

We can use this endpoint to do this.
