### ImageMagick version

7.1.0-62

### Operating system

Windows

### Operating system, version and so on

10

### Description

The documentation page (https://imagemagick.org/script/defines.php) is missing command-line Defines for the Webp format.

For example: `-define webp:lossless=true` is not listed in the documentation even though it is a working parameter in ImageMagick .

### Steps to Reproduce

Convert an image with and without the option `-define webp:lossless=true`:

```
    convert input.png -define webp:lossless=true output.webp
    convert input.png output.webp
```

See that the images differ and that the option does not appear in the documentation at https://imagemagick.org/script/defines.php
