This is the sort of tedius, repetitive stuff that AI is well suited for.
I provided a single JSON example.
I uploaded your screenshot, with the unnecessary stuff cropped off.

The entire process probably took less than 5 minutes.
Here is the result ready to paste into your New Doc Sizes.json file. EDIT: Now updated to contain all 21 presets:
