Describe SSL/TLS configuration

https://pedia.altinn.cloud/sec/security-architecture/data-security/encryption-transit/ (or a page referred to from this page) should be updated with information on how SSL/TLS is configured. Once approved, relevant parts should be migrated from pedia to docs.

Start by reviewing the referenced pedia page on encryption in transit and determine where SSL/TLS configuration information belongs. Document the approved configuration on that page or a related page, then migrate the relevant approved content from pedia to the Altinn Studio docs. Done means the configuration is documented and the migration is complete.
