[DOC] Process._fork does not get called by Process.daemon
As discussed in [Bug #18911], I'm adding some documentation to `Process._fork` to clarify that it is not expected to cover calls to `Process.daemon`. [Bug #18911]: https://bugs.ruby-lang.org/issues/18911 Co-authored-by: Yusuke Endoh <mame@ruby-lang.org>

* This method is not for casual code but for application monitoring
|
||||
* libraries. You can add custom code before and after fork events
|
||||
* by overriding this method.
|
||||
*
|
||||
* Note: Process.daemon may be implemented using fork(2) BUT does not go
|
||||
* through this method.
|
||||
* Thus, depending on your reason to hook into this method, you
|
||||
* may also want to hook into that one.
|
||||
* See {this issue}[https://bugs.ruby-lang.org/issues/18911] for a
|
||||
* more detailed discussion of this.
