Config export ordering is non-deterministic

[injust]

• [x] This is a new bug that hasn't been documented in a closed issue or in the Readme.

macOS version: Sequoia 15.0 Rectangle version: v0.83 (89)

When exporting Rectangle's config, the order of the values in defaults.landscapeSnapAreas.string seems to be non-deterministic.

This is a bit confusing if you diff the file. Is it possible to make the order of the output consistent?

An example diff:

diff --git i/RectangleConfig.json w/RectangleConfig.json
