Public bug reported:
Adding the apt key for `ppa:libreoffice/ppa` fails on newer systems
(specifically Ubuntu 22.04 Pro w/ `$ pro enable fips-updates`) that
removed support for the rsa1024 algorithm.
```
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv-keys

Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead
(see apt-key(8)).

I've inspected the key after adding it on a system that supports
rsa1024.
```

Can the key be updated to use rsa4096?
