Incorrect typehint for $color and $backgroundColor

[mundschenk-at]

The parameters $color and $backgroundColor are typehinted as string, while they also take an RGB array. The @param annotation should be changed to string|array.

✅ Resolved in v3.0.0 #82

Colors now properly accept both string and array formats via the Color value object:

$builder->color('#3498db');      // Hex string
$builder->color('fff');          // Short hex
$builder->color([52, 152, 219]); // RGB array
