Data analysis / RapidPE-Rift

Minor edits to the new text in 'Data analysis / Inference'

RapidPE-RIFT [9] [10] provides source classification by estimating source probabilities assuming astrophysical origin and renormalizes them by the terrestrial probability (Terrestrial) estimated by the search pipelines for the preferred event.

• 'Renormalize' has a technical meaning, which is not what we want to say here. In any case the text doesn't really explain what we do. As long as we don't want to actually give the calculation details, I suggest '; these probabilities are then combined with the probability of terrestrial origin ...' - since this combination step isn't really part of the RapidPE method.
• Make the first occurrence of 'terrestrial' into a hyperlink, rather than putting the word twice but the second time in brackets as at present.
