Improve docker auto builds (#2078)

## Issue Addressed

N/A

## Proposed Changes

- hardcode `ubuntu-18.04` -- I don't think this was causing us issues, but github actions is in the process of migrating `ubuntu-latest` from Ubuntu 18 -> 20.. so just in case
- different source of emulation dependencies -> https://github.com/tonistiigi/binfmt 
  - this one is explicitly referenced in the `buildx` github docs
- install emulation dependencies and run `docker buildx` in the same `run` command
- enable `buildx` with  `DOCKER_CLI_EXPERIMENTAL: enabled` rather than re-building it
