Upgrade Narayana to 6.0.0.Final

There is a new version of Narayana available (WildFly is currently on 6.0.0.CR1). This new version is similar to CR1 (see diff for what we changed).

The component upgrade will also include version 8.0.0.Final of JBoss Transaction SPI which natively supports Jakarta APIs, previous versions used the Ecliplse byte code transformer and those are no longer produced (ie we no longer produce the artifacts with the "-jakarta" sufixes which means there will no longer be any jboss-transaction-spi-jakarta versions).
