Add PHPUnit 10+ attributes

[ruudk]

Fixes #1359

While upgrading to PHPUnit 11 I noticed the following deprecation:

Metadata in doc-comments is deprecated and will no longer be supported in PHPUnit 12. Update your test code to use attributes instead.

If we add the attribute too, it stops complaining. So this most be a way to support PHPUnit 11 and older versions.

If we ship this, we reduce a few errors. Most of the things just work fine.

Looks good to me, @ruudk

Thank you.

GitHub is partially down right now,

"degraded performance for Pull Requests and Actions:" https://www.githubstatus.com/incidents/wcl1sw4mzg60

I’ll restart GitHub Action and merge this once CI completes.

for the record...

When both /** @before */ and #[Before] are used then 1) the before-test method is called only once and 2) the deprecation is not emitted.
