Add checks for TypeDoc compliance

[mcmire]

We want to make sure that for a given project:

• The project contains typedoc as a dev dependency, and the versions match the same dev dependencies as in the module template.
• The project contains a typedoc.json, and the content of this file matches the same as in the module template.
• The project contains the same build:docs package script as in the module template.

Note that there are other TypeDoc-related considerations that we could address in this PR but do not need to:

• The publish-docs GitHub workflow in the module template uses TypeDoc to generate document and publish it, using the build:docs package script. We want to make sure that projects have this workflow too, but checking this effectively is tricky. We can check that the workflow file is present but how do we know that it's getting run? So we can either think about this either in a separate PR, or we can handle this in Add checks for general module template adherence #6.

In this ticket we are not checking the workflow. See Elliot's comment.
