[CCXDEV-12111] Adapt run_in_docker.sh script to Github workflows

[epapbak]

Description

Remove the -it parameters from the docker exec command used to run the BDD tests. It's a leftover from using the command in manual tests, and it does not work in GitHub workflows as the pseudo TTY is not allocated.

Fixes CCXDEV-12111

Type of change

• Bug fix (non-breaking change which fixes an issue)

Checklist

• Pylint passes for Python sources
• sources has been pre-processed by Black
