Description

While working through #37929 I noticed that the tests in the docgen package
read fixture data manually by chaining JSON.parse() and fs.readFileSync(),
often at times separated by a number of lines.

In this patch we're replacing those with the more natural require() statement
which removes noise from the test modules and hopefully will also remove a point
of confusion for those coming in to modify it. We shouldn't have to ask, "why is
this code doing something that looks normal but is doing it in a notably different
manner?"

After reviewing the history of the work, initially introduced in #13329, I could
find no explanation for the approach and found no discussion about it in the PR.

How has this been tested?

Ran the test suite and yarn api-docs:ref and yarn api-docs:blocks and yarn api-docs:theme-ref and compared output to ensure no changes appeared.

Types of changes

Refactor to remove some complexity in an already-confusing test module and run with an idiomatic solution.

Checklist:

  • My code is tested.
  • My code follows the WordPress code style.
  • My code follows the accessibility standards.
  • I've tested my changes with keyboard and screen readers.
  • My code has proper inline documentation.
  • I've included developer documentation if appropriate.
  • I've updated all React Native files affected by any refactorings/renamings in this PR (please manually search all *.native.js files for terms that need renaming or removal).
  • I've updated related schemas if appropriate.

Nice refactoring 👍

I also can’t find any benefit of keeping the old approach.
