This was only the case in a fallback path (ie. when the user provides a
`json` file with an old or computed format from an external source).
Closes#20844.
SixLabors moved their data types around in a recent update (see
https://github.com/ppy/osu-framework/pull/4025) and it was deemed that
we should prefer `System.Drawing` primitives where possible.
This was applied to the tournament client via
https://github.com/ppy/osu/pull/11072 without correct consideration
given to the fact that we serialize these types.
`System.Drawing.Point` serializes into a comma separated string, which
seems to be less correct than what we had, so I've switched back to the
old format for the time being. We can reasses this in the future; the
main goal here is to restore usability to the tournament client.
Closes#11443.
