Bug#1030009: www.debian.org: addition of non-free-firmware for bookworm and higher

Hello
I have reviewed Holger's proposals in the branch GR-non-free-firmware (thanks a 
lot!) and added updates to some other files, and updated the 
https://deb.li/1030009 pad

The current status, as I see, is the following:

* I agree with all the files reviewed with comment that don't need update
* I agree with all the update proposals that are currently in the branch. The 
files releases/bookworm/errata.wml and devel/debian-installer/index.wml are 
already updated in the master branch so when merging we should discard changes 
in the  GR-non-free-firmware affecting these files and keep the ones in master.
* I agree that we shouldn't change Bugs/server-request.wml without checking 
first with BTS team if the BTS already knows about non-free-firmware. So leaving 
this for "after the Debian 12 release".
* No idea if packages.debian.org already knows and allows to search about 
non-free-firmware but we can incorporate the updates to our files as Computer 
Enthusiastic (in CC) suggested and Holger committed, and then after the release 
we can try to help to update packages.d.o if needed.
* The scripts that produce the data for the l10n dashboards would need update so 
I'm leaving international/l10n aside for now, I just added non-free-firmware in 
the synonyms list, and to the ddtp.wml file that says that non-free is not 
handled due to possible license issues ( adding here non-free-firmware does not 
harm, so I added it).
* It's been suggested that we may need to update intro/why_debian.wml to reflect 
the changes in the GR about non-free-firmware but I have reviewed the file and I 
don't find the reason why whe should update it.
* It's been suggested that we change the links 
https://cdimage.debian.org/cdimage/unofficial/non-free/firmware/ for 
https://cdimage.debian.org/cdimage/firmware/ (starting with bookworm) but since 
currently both URLs serve the same files, I'd would do it after the branch is 
merged, since many links are going away in the merge.

So, in summary, I think we can merge the branch into master when we see suitable 
(1) and just need to be careful about not overwriting the files 
releases/bookworm/errata.wml and devel/debian-installer/index.wml.

(1) when we see suitable: I guess right after the Debian 12 images are ready for 
download as "stable" release, but in fact I'm not sure how to handle this and 
the translations. I am available to merge the branch this weekend when the 
website is updated to the release, and can try to update the languages that have 
no active translator these days. For the rest, if nobody proposes better way, I 
will send a mail to debian-i18n and debian-www explaining that this branch will 
be merged during the weekend so people are prepared to do their changes in the 
corresponding language folder (if they choose to advance work in the branch, it 
will be merged and I'll try to update the commit-hashes later).

Kind regards,
