James O'Beirne dff7ed5732 test: add an easy way to run linters locally
Adds a Dockerfile configuration
that allows straightforward running of linters with compatible versions
locally. This removes a ton of annoyance when trying to appease CI,
because many of the linter versions are quite old and difficult to
maintain locally.

I realize that people may not be thrilled to more ancillary tooling to
the repo, but I think this makes a lot of sense given the linter
versions listed in this container configuration are dictated by this
repo (within the CI configuration), so having these things live in
two separate places is a recipe for version mismatches.

Eventually we can likely just use this container on CI directly to avoid
any chance of inconsistencies between local dev experience and CI.

# entire repo as docker context during build; if it lived elsewhere, it wouldn't be
# able to make back-references to pull in the install scripts. So here it lives.
