Use a pre-built go executable for deployments

[DarVoid]

Currently, the deploy action pulls a Golang base image and runs the Dockerfile to compile the executable. This means every time we use the action, we're unnecessarily rebuilding the executable.

Instead, we could optimize this by pulling a minimal image with just the prebuilt Go executable. This would reduce build time, minimize dependencies, and improve efficiency without changing functionality.

Would you consider updating the workflow to use a prebuilt binary instead? Happy to discuss possible solutions!
