Make capitalisation consistent when reading data point changes (#14045)
A translator on the mailing list raised an issue, pointing out that the capitalization is inconsistent for these strings.
Increased by {incrementValue} from point {previousIndex}, - on beginning of sentence (I) is capitalised.
decreased by {decrementValue} from point {previousIndex}, - on beginning of sentence (d) is not capitalised
These should both begin with lowercase, as they are comma separated phrases as part of a longer message.
