[docker] Updated devbox install links for docker images (#2011)

## Summary
Updated devbox install link for docker image.
After merging this we will release a new docker image, and that should
upgrade the launcher version to 0.2.2. Currently, docker images have
0.2.1 or 0.2.0 for launchers due to devbox image being built and pushed
to dockerhub before launcher changes.

## How was it tested?
N/A
