Remove unnecessary files from composer package

[jlherren]

These files make no sense to be distributed as part of the composer package.

If desired I can make the same change also for 1.x, where there are two additional files to be removed.

Seems okay, but I need to read up on this. Should .readthedocs.yaml also be added to your list?

I don't know about earlier releases. I will give it some thought. What are the additional files you would like to exclude for release 1?

[jlherren]

Version 1.29.5 also ships with:

• phpstan-conditional.php
• phpunit10.xml.dist

However, 3.5.0 does not ship with .readthedocs.yaml and I don't see why not, so perhaps there's more going on that just what's in .gitattributes.

I need to resolve this question before I merge. When I run git archive on the current version, it includes .readthedocs.yaml. When I download the zip for release 3.5.0, it contains .readthedocs.yaml. When I do composer require phpoffice/phpspreadsheet, .readthedocs.yaml is part of it. Is there some other action that you can take which will download the release without that file?

[jlherren]

My bad, I didn't realize that the screenshot was from 1.29.5, which in fact did not have .readthedocs.yml yet. I do get it on 3.5.0.

I updated the PR.

Thank you for your contribution.
