Subject: [PATCH 1/2] refactor: alphabetize compression algorithms

Alphabetize compression algorithms in the comments for
`DataBackupConfiguration` and `WalBackupConfiguration`.
This keeps the order consistent with the Enums below
the comments.

Subject: [PATCH 2/2] fix: allow zstd compression for base backups

Barman 3.20.0 added `--zstd` to barman-cloud-backup
(EnterpriseDB/barman@0aa2070). Put `zstd` back in the
`DataBackupConfiguration` Enum; it was removed in #89 when no
base-backup tool accepted it.

Closes #305
