Can you just rename the last command result as res instead of res2

Pull request overview
This PR updates the TestBuildTLS e2e test to avoid host port collisions on TLS-enabled Docker hosts by switching the Docker-in-Docker (dind) container to use an ephemeral (random) mapped host port and then discovering that port via docker inspect before creating the Docker context.
Changes:
- Map dind’s container port
2376/tcpto a random host port on127.0.0.1instead of hard-coding2376:2376. - Query the selected host port from
docker inspectand use it when creating the Docker context for the test.

What I did
Use random host port to fix TestBuildTLS on TLS-enabled hosts.
Otherwise test fails with:
docker: Error response from daemon: failed to set up container networking: driver failed programming external connectivity on endpoint e2e-dind-builder (b6c6ef56255e36311caf121fdc29e0ad85f608a89aacafd152dd489a71fb0863): Bind for 0.0.0.0:2376 failed: port is already allocatedRelated issue
