#0: Add bc to docker container for pgm dispatch math

[tt-rkim]

Ticket

Blocking @jbaumanTT

Problem description

the container doesn't come with bc by default

What's changed

Added bc for math

I'm wondering if we should take it out later and put it directly as a sudo apt install command in the workflow, so we don't set the precedent of chucking stuff into the image.
