The binary is built in debug mode (without --release). This is what accounts primarily for shortening the workflow cycle.

This build was not necessary.

jq wasn't used in the relayer image.

The idea of building the relayer inside the Docker container was to avoid any side effects of building in one platform but since the Docker container is Debian and the CI uses Ubuntu, I think it's all good and the speed improvement are great

Hmm this is something I overlooked!

In a future PR, maybe we run the relayer binary directly from Github actions? This would further simplify the workflow (and probably reduce the time).
