[vpdq] Add vpdq Dockerfile for development

[ianwal]

Summary

• Add Dockerfile for development convenience
  • Note: User still needs to setup and use venv for the Python bindings. This container is just for setting up an environment. But pip install -e . works out the box for the bindings.
• Add devcontainer config to use the Dockerfile with VSCode
  • Autogenerated by the devcontainer VSCode extension.
• Add Docker documentation
• Added the missing pkg-config to dependencies
• Fixed some documentation markdown issues
  • markdownlint VSCode extension is very handy.

Not sure the best practice if other devcontainers are added to the repo, but for now this works.

Test Plan

Markdown renders as expected.

Container builds successfully.

vpdq and Python bindings build successfully and pass all tests in the container.

No problem, thanks for giving good feedback in these PRs! Working on this and my project that uses was a huge help in getting my firmware engineer job, so I like coming back and making some improvements to it as I learn more over time 🙂
