Remove unused docker workflow (#5349)

# Description of Changes

<!-- Please describe your change, mention any related tickets, and so on
here. -->

We believe this docker build is completely unused. This docker container
is different than the docker build that we send out for releases which
is the one users actually end up using. This specific docker build used
to be for internal deploys but we have not used it in a very long time
now, probably more than a year or two.

# API and ABI breaking changes

None - this is just a CI change.

<!-- If this is an API or ABI breaking change, please apply the
corresponding GitHub label. -->

# Expected complexity level and risk

1 - just a CI change

<!--
How complicated do you think these changes are? Grade on a scale from 1
to 5,
where 1 is a trivial change, and 5 is a deep-reaching and complex
change.

This complexity rating applies not only to the complexity apparent in
the diff,
but also to its interactions with existing and future code.

If you answered more than a 2, explain what is complex about the PR,
and what other components it interacts with in potentially concerning
ways. -->

# Testing

<!-- Describe any testing you've done, and any testing you'd like your
reviewers to do,
so that you're confident that all the changes work as expected! -->

- Not tested but we sync'd on this in the discord and there were no
objections from the devops team or @joshua-spacetime .
