7.4.z.GA Wrong property name in "Transaction Troubleshooting Guide: Configuring Transactions"

In reference to https://issues.jboss.org/browse/JBEAP-14556, the system property referred to as "periodicRecoveryInitializationOffset" is named "periodicRecoveryInitilizationOffset" in the Bean class (https://github.com/jbosstm/narayana/blob/master/ArjunaCore/arjuna/classes/com/arjuna/ats/arjuna/common/RecoveryEnvironmentBean.java#L47)
Although periodicRecoveryInitilizationOffset contains a grammar typo, it has been used like that elsewhere in the documentation (e.g. http://narayana.io/docs/product/index.html) so we should refer to it like that, to avoid confusion.
