fix (bottomsheet ios) corrected width on safe areas

[alexander-mai]

• the right and bottom values erroneously subtract the left and top distances, respectively
• the error only appears when there are safe areas on the sides, for example on an iPhone X
• removing the subtraction is correcting this issue
