fix(css): clarify atan2() return value documentation

[abhinav12222363]

This PR fixes incorrect wording in the CSS atan2() documentation.

The original text incorrectly stated that the function returns “the number of radians representing an angle between -180deg and 180deg”, which mixes units and caused confusion.

Updated the sentence to:

• Remove the incorrect reference to radians
• Clarify that the function returns an angle between -180deg and 180deg, as suggested by the MDN maintainer in issue atan2() calculation always returns an <angle> in degrees, not radians #42283.
