linux-firmware: Update version from 20220411 to 20230625-39-g59fbffa9
9f13533 
This contains updated microcode updates for [Zenbleed][1], that can
hopefully be applied on running systems via [late loading][2].

    $ echo 1 | sudo tee /sys/devices/system/cpu/microcode/reload

Also remove comment with incorrect instructions, how this bee file was
created.

Resolves: mariux64/mariux64-issues#82

Would be great to get this tested on Zen 2 systems.
