So, does new kernel versions just copy this microcode update file in
/etc/firmware folder or new
instructions are replaced in assembly code ?

The kernel doesn't load microcode automatically but it can provide a
device to allow userspace to trigger a microcode update (via
/dev/cpu/microcode ). On boot the patching process is normally started
by an initscript. See http://www.urbanmyth.org/microcode/ for details.
