dev/core#5611 Exclude tests and tools directories from exports

[colemanw]

Overview

Avoid distributing test files in packaged downloads.
See https://lab.civicrm.org/dev/core/-/issues/5611

Technical Details

I'm not sure if this only fixes composer-based installs and we also need to do something for our packaging script to avoid putting ext/*/tests directories in the zip/tar files.

• Before this PR can be merged, it needs to be reviewed. Please keep in mind that reviewers are volunteers, and their response time can vary from a few hours to a few weeks depending on their availability and their knowledge of this particular part of CiviCRM.
• A great way to speed up this process is to "trade reviews" with someone - find an open PR that you feel able to review, and leave a comment like "I'm reviewing this now, could you please review mine?" (include a link to yours). You don't have to wait for a response to get started (and you don't have to stop at one!) the more you review, the faster this process goes for everyone 😄
