Update outdated GPG signing key in tutorial

[darthmassari]

The GPG verification instructions on installing Elements are currently outdated. The guide instructs users to import key DE10E82629A8CAD55B700B972F2A88D7F8D68E87, but the latest SHA256SUMS.asc is signed with key BD0F3062F87842410B06A0432F656B0610604482.

Steps to reproduce:

• Follow the current guide to import the key:

gpg --keyserver keyserver.ubuntu.com --recv-keys DE10E82629A8CAD55B700B972F2A88D7F8D68E87
gpg: key 2A57E0A610D7F19C: public key "Steven Roose <steven@stevenroose.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1

• Attempt to verify the latest release:

gpg --verify SHA256SUMS.asc

• Verification fails with:

gpg: Signature made lun 13 apr 2026, 18:06:31 CEST
gpg:                using RSA key BD0F3062F87842410B06A0432F656B0610604482
gpg: Can't check signature: No public key
