Removing "-t" flag to allow github actions to run kb-sdk

[ialarmedalien]

GitHub Actions cannot run kb-sdk when it is in a docker container because the entrypoint script adds the -t flag to the docker command (to add a TTY-type interface to the container), which causes GitHub Actions to error out. Since the commands that the entry point script is adding can't be run interactively, the -t flag can be safely removed.

I had to workaround this on some Github actions stuff by editing the genscript results. This would be great to merge before the next image release.

LGTM

This eliminates the need for a custom kb-sdk command, like I've been using in the SDK Tests Action as seen here. Excellent!
