Michael Taylor dcd2f33f7c CODEBASE: Update api-documentor and api-extractor (#2320)
* Update api-documentor and api-extractor. #1566 follow-up.

I have verified that the HTML/markdown table generation bug in
[#4878](https://github.com/microsoft/rushstack/issues/4878) in rushstack
for api-documentor has been fixed as per rushstack#5256. The testcase
[repro](https://github.com/catloversg/api-documenter-bug-pr-4578) now
produces the correct expected output.

I have confirmed that the generated output in bitburner from
`npm run doc` now generated HTML tables, and correctly inserts
a blank line between the </table> and the follow line (e.g. Returns).

Stylisticly it could use some whitespace, but it is correctly rendered.

This commit is only the updated packages, not the updated generated
documentation. I assume that is automatically generated by the GitHub
workflow.

* Follow up to 5f732a6f35, include `npm run doc` changed docs.

* Add missing license info

* Fix React warning
