DOC: Specify range for numpy.angle

Fixes #7426

I think you should keep the word "counterclockwise" here

[kritisingh1]

When the angle is from (-pi, 0) it is a clockwise angle from the positive real axis. Should I specify the direction for both (-pi,0] and [0,pi] then? @eric-wieser

[eric-wieser]

The direction of the numeric value is always counterclockwise. If angle returns -90°, it means -90° counterclockwise. Yes, this can also be expressed as a 90° angle clockwise, but that's irrelevant because it returns -90 not +90.
