Adding ffmpeg into the Ubuntu 22 container

[js333031]

I've tried adding ffmpeg pkg into the container but the build fails.

python3 docker_openvino.py build --file "dockerfiles/ubuntu22/openvino_cg_dev_2023.0.0.dockerfile" -os ubuntu22 -dist dev -p 2023.0.0

I tried following line at multiple places in dockerfiles/ubuntu22/openvino_cg_dev_2023.0.0.dockerfile:

RUN apt-get update && apt-get install -y ffmpeg

Error during build:
