Fidel Docs variability with authorisation vs authorization vs auth

[taboca]

*This feedback is based on a first reading experience, when I found Fidel Docs as part of an interview process; I decided to annotate some points— things I may perceived as ambiguous. Keep in mind that it's my own view and not exactly a problem in the documentation. *

Hypothesis problem

From earlier first-read experience I may stumbled in some costy reading which I was at the time not sure if these were because of UI or what.

Cases were:

• “ real-time authorisation transaction”
• “ real-time authorization Transactions”
• "auth transaction"
• "authorisation transaction"
