Correction for Gentoo entry: dev-util/scons -> dev-build/scons

[pkartsev]

Your Godot version:

4.2.1

Issue description:

https://docs.godotengine.org/en/latest/contributing/development/compiling/compiling_for_linuxbsd.html

tab for Gentoo:

emerge -an \
  dev-util/scons \
  x11-libs/libX11 \
  x11-libs/libXcursor \
  x11-libs/libXinerama \
  x11-libs/libXi \
  media-libs/mesa \
  media-libs/glu \
  media-libs/alsa-lib \
  media-sound/pulseaudio

actually valid ID for scons in Gentoo is dev-build/scons , not dev-util/scons (at least today as I entered this command):

emerge: there are no ebuilds to satisfy "dev-util/scons".

emerge: searching for similar names...

emerge: Maybe you meant any of these: dev-build/scons, dev-util/pscan, dev-util/conan?
