(closes: #1043381)
* WARNING: for proper operation on AMD Genoa and Bergamo processors,
either up-to-date BIOS (with AGESA 1.0.0.8 or newer) or up-to-date
Linux kernels (minimal versions on each active Linux stable branch:
v4.19.289 v5.4.250 v5.10.187 v5.15.120 v6.1.37 v6.3.11 v6.4.1)
are *required*

* debian/NEWS: AMD Genoa/Bergamo kernel version restrictions
* debian/changelog: update entry for release 3.20230719.1, noting
that it included fixes for "AMD Inception" for Zen3 processors.
We did not know about AMD Inception at the time, but we always
include all available microcode updates when issuing a new
package, so we lucked out.
* debian/changelog: correct some information in 3.20230808.1
entry and reupload as 3.20230808.1.1. There's no Zenbleed
for Zen4... oops!
