This reverts commit b10f1ca3a6.

PR #73978 introduced a regression.
Unfortunately this PR cannot be reverted without reverting also
Let's revert both PRs to stabilize main again towards the 3.7 release.

@ -244,34 +244,26 @@ POSIX_SIGNALS
Signal services are a basic mechanism within POSIX-based systems and are
required for error and event handling.
.. note::
As processes are not yet supported in Zephyr, the ISO C functions ``abort()``, ``signal()``,
and ``raise()``, as well as the other POSIX functions listed below, may exhibit undefined
behaviour. The POSIX functions ``kill()``, ``pause()``, ``sigaction()``, ``sigpending()``,
``sigsuspend()``, and ``sigwait()`` are implemented to ensure that conformant applications can
link, but they are expected to fail, setting errno to ``ENOSYS``
