Unknown encryption method

Detects non-existing encryption methods references in OpenTofu encryption block configuration. For the following code:

      terraform {
        encryption {
          key_provider "pbkdf2" "foo" {
            # Configuration parameters
          }
          method "aes_gcm" "yourname2" {
            keys = key_provider.pbkdf2.foo
          }
        }
      }
    

We should check if the method name is correct.
