[Content]: Group traits to clarify whether 'revenue' or 'total billed' are reserved

What article on segment.com/docs is affected?

https://segment.com/docs/connections/spec/group/#traits

What part(s) of the article would you like to see updated?

The example payloads on the Group calls documentation include a Group trait called 'total billed'.

The traits section includes the following paragraph, referring to a 'revenue' reserved trait.

Note: You might be used to some destinations recognizing special properties differently. For example, Mixpanel has a special track_charges method for accepting revenue. Luckily, you don’t have to worry about those inconsistencies. Just pass along revenue. Segment handles all of the destination-specific conversions for you automatically. Same goes for the rest of the reserved properties.

However neither 'total billed' or 'revenue' are mentioned anywhere else on the page, and neither of them are mentioned as in the table of reserved traits. Clarification of whether either/both/neither of these traits are reserved would be appreciated.
