[imgcodecs] fix to supported depth for TIFF #26509
Description
Describe the doc issue
At document, TIFF encoder supports 'CV_8U', 'CV_16U' and 'CV_32F'.
https://docs.opencv.org/4.x/d4/da8/group__imgcodecs.html#ga8ac397bd09e48851665edbe12aa28f25
With TIFF encoder, 8-bit unsigned (CV_8U), 16-bit unsigned (CV_16U), 32-bit float (CV_32F) and 64-bit float (CV_64F) images can be saved.
However TIFF Encoder supports CV_8S, CV_16S, CV_32S and CV_64F too,
