TP Integration Tests GHA still starts Riak container

[zrhoffman]

I'm submitting a ...

• improvement request (usability, performance, tech debt, etc.)

Traffic Control components affected ...

• GitHub Actions

Current behavior:

The tp-integration-tests GitHub Action starts but does not use a Riak Docker container.

New behavior:

The Riak container should be removed.

Minimal reproduction of the problem with instructions:

trafficcontrol/.github/actions/tp-integration-tests/entrypoint.sh

Lines 133 to 138 in 295c31e

	docker run \
	--detach \
	--env-file="${ciab_dir}/variables.env" \
	--hostname="${trafficvault}.infra.ciab.test" \
	--name="$trafficvault" \
	--publish=8087:8087 \

I'll take this one.
