"minecraft:food" item component's property "saturation_modifier" is not working as intended

`minecraft:food` component used for items with the newer format version 1.16.100+ has a property called `saturation_modifier` in which is not working as intended.

On the official documentation, the property is documented as follows:

saturation_modifier

Saturation Modifier is used in this formula (nutrition * saturation_modifier * 2). Default value is set to 0.6.

Minimum value: 0.00

Type: float

 

However, upon testing it does not seem to work as intended and seems to only accept predefined strings: 

• "poor";
• "low";
• "normal";
• "high";
• "good";
• "max"; and
• "supernatural"

This format was originally used in the older format version 1.10. In addition, I already have necessary "Experiments" toggled enabled so that the game would (hopefully) parse 1.16.100+ format version items in properly.

Repro steps

1. Download the attached addon file and import it to a new world
2. Get the content log error and item will not parse the `saturation_modifier` properly
3. You may edit the file (BP/items/cook/tasty_food_1.json) and change the value to either any float value and it will not work as documented.
