added_bytes metric in prometheus file is always zero

[nwinkelstraeter]

All others metrics are populated with plausible values.
I did a little bit of research and I think this is related to a change of wording introduced in restic 0.14.0 (restic/restic#3741)
That PR changed repo to repository in some places and then this line

resticprofile/shell/plain_summary.go

Line 28 in ae9554a

n, err := fmt.Sscanf(scanner.Text(), "Added to the repo: %f %3s", &rawBytes, &unit)

does not parse the output correctly anymore.
