Test files in distributed package

[laoneo]

The release downloads do contain Test classes which should not be shipped with production code. These are:

• /libraries/vendor/symfony/http-client-contracts/Test
• /libraries/vendor/symfony/http-client/Test

Not sure if there are more, but found these by accident.

These should be added to build\build.php

[brianteeman]

and then for upgrades they will need to be added to the list of files to remove in administrator/components/com_admin/script.php

Found at least two more - we were excluding Tests from the symfony libraries but it seems they are also using Test

#46765 (comment)

It needs to be checked separately for 5.4-dev, 6.0-dev and 6.1-dev as we have different dependency versions. Some 3rd party dependencies fixed that development and testing files are distirbuted in their new versions.

At the end if we have a list for each branch, I can make the necessary PRs.

This can be closed as it is resolved with #46765
