Consider r-using the "relevant to understanding the result" wording also in notifications/relatedLocation

[sthagen]

Kalle Olavi Niemitalo suggested in discussing pull request #643 where we add the relatedLocation field to the notification object:

I meant, I'd like this paragraph to use the "relevant to understanding the result" wording:

sarif-spec/sarif-2.2/prose/edit/src/file-format-58-notification-object.md

Line 106 in 7fde936

A `notification` object **MAY** contain a property named `relatedLocations` whose value is an array of zero or more unique ([sec](#array-properties-with-unique-values)) `location` objects ([sec](#location-object)) that identify those locations to which the condition described by the notification applies.

instead of saying that the condition "applies" to the related locations. That way, it would be consistent with the complicated second part that says there may be locations to which the condition does not apply, and also consistent with how the relatedLocations property of the result object is described.
