Add more linting workflows

[CarrotManMatt]

Add linters for more file types: Dockerfile, YAML, etc.

Some libraries already exist:

• https://github.com/adrienverge/yamllint
• https://github.com/hadolint/hadolint (possibly https://github.com/AleksaC/hadolint-py)
• https://pre-commit.ci/

Pre-commit hooks should also be added.
