docs: Update --listTests docs to reflect what it does

[Gerrit0]

Summary

The description of --listTests on the website currently implies that --listTests will give output describing all tests as JSON. However, when trying to use it, I found that it did not do this, instead only printing out all test files, one per line. (If also given --json Jest produces JSON, but not by default)

Hi @Gerrit0!

Thank you for your pull request and welcome to our community.

Action Required

In order to merge any pull request (code, docs, etc.), we require contributors to sign our Contributor License Agreement, and we don't seem to have one on file for you.

Process

In order for us to review and merge your suggested changes, please sign at https://code.facebook.com/cla. If you are contributing on behalf of someone else (eg your employer), the individual CLA may not be sufficient and your employer may need to sign the corporate CLA.

Once the CLA is signed, our tooling will perform checks and validations. Afterwards, the pull request will be tagged with CLA signed. The tagging process may take up to 1 hour after signing. Please give it that time before contacting us about it.

If you have received this in error or have any questions, please contact us at cla@fb.com. Thanks!
