apt key uses deprecated rsa1024 algorithm

[Jake Lepere]

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 83FBA1751378B444
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.

```
$ sudo apt-key list

Can the key be updated to use rsa4096?

Hi, this is a known issue and we are working on rotating the keys of the affected PPAs with 1024-bit RSA keys to 4096-bit RSA keys.
