v6

[andyundso]

This ticket should hold potential ideas for a v6 release, probably timed with the removal of Datatrans' XML API removal (3rd of June, 2024)

• Drop XML API code
• Drop Datatrans::JSON::Transaction::Authorize (forces release of Alias Datatrans::JSON::Transaction::Authorize to Datatrans::JSON::Transaction::Initialize #58 in a prior release)
• Drop support for Rails 5.2 and 6.0
• Alias Datatrans::JSON::Transaction::MerchantAuthorize to Datatrans::JSON::Transaction::Authorize
