docs: drop uncommon spelled out GCM

It does not help users if that is spelled out, and its not a common
use of GCM, and especially in the AES 256 context its clear what is
meant. The link to Wikipedia stays, so interested people can still
read up on it and others get a better overview due to the text being
more concise.

 :Compression: The ultra-fast Zstandard_ compression is able to compress
    several gigabytes of data per second.
 
-:Encryption: Backups can be encrypted on the client-side, using AES-256 in
-   Galois/Counter Mode (GCM_). This authenticated encryption (AE_) mode
-   provides very high performance on modern hardware. In addition to client-side
-   encryption, all data is transferred via a secure TLS connection.
