Consider updating Wiki for rust issue 39364

[vulns-are-features-too]

https://github.com/Nukesor/pueue/wiki/Advanced-usage#scripting mentions that scripts may need to sleep until rust issue 39364 is fixed.
The issue has been closed as completed. Is the sleep still necessary, or will you remove that little note?

It's actually still relevant due to the current architecture of pueue.

The need for sleep (:D) will become obsolete as soon as this: #540 (comment) is implemented.
Once that has been done, a lot of documentation needs to be updated anyway, including the wiki.

Anyhow, I removed the mention of the rust issue for now :)
