Undesired behavior for Text adjustsFontSizeToFit on iOS

[alfonsocj]

RN Version: 0.70.3

👋 The desired behavior for adjustsFontSizeToFit is to keep the font size as specified unless there's not enough space.

It looks like adjustsFontSizeToFit also scales up (instead of just scaling down like in the Paper implementation) when the new arch is enabled.

Here's a snack with the code I used to test it https://snack.expo.dev/@alfonsocj/spunky-graham-crackers.

Paper	Fabric

It looks like the Paper implementation sets the maximum font size to the textAttributes.effectiveFont.pointSize while the fabric implementation checks for the paragraphAttributes.maximumFontSize which is not set and sets the maximum to 96.0.
