config-json.md: files.invalidator not documented?

[fapdash]

I just saw this PR utilizing files.invalidator and it doesn't seem to be documented in https://github.com/exercism/docs/blob/43a2d226da5e2c8631de8d5006adb9c60ccf877b/building/tracks/config-json.md.

Is this on purpose or should this be added?

Is this on purpose or should this be added?

I believe it's an oversight - it should be added. It's documented elsewhere:
