Stream.filterNot does not exist but still referenced from Scaladocs

[satorg]

There is a couple of references to filterNot in Scaladocs:
https://github.com/typelevel/fs2/blob/2efbedeb8316bf7b83f01964733089df7a883291/core/shared/src/main/scala/fs2/Stream.scala#L1112C31-L1123

But there's no the filterNot function per se.

I think it would be fair either to add filterNot method or to rephrase the docs and hence to avoid any confusion about it.
Not sure which is better though.

Also, it was mentioned here:
