GD Extension Requirement

[SwiseWeb]

Description

Now that GD is a required extension in Craft 5.9+ as outlined in this issue, seems like the System Report should be updated as well to reflect that since using only ImageMagick is no longer supported.

Lines 115 to 120 in 3b1f239

	array(
	'name' => 'GD extension or ImageMagick extension',
	'mandatory' => false,
	'condition' => extension_loaded('gd') || (extension_loaded('imagick') && !empty(\Imagick::queryFormats())),
	'memo' => 'When using Craft\'s default image transformer, the <a rel="noopener" target="_blank" href="https://php.net/manual/en/book.image.php">GD</a> or <a rel="noopener" target="_blank" href="https://php.net/manual/en/book.imagick.php">ImageMagick</a> extension is required. ImageMagick is recommended as it adds animated GIF support, and preserves 8-bit and 24-bit PNGs during image transforms.'
	),

Steps to reproduce

1. Install Craft 5.9+ on a container with only ImageMagick enabled. GD is a composer requirement, but it's possible to install the dependencies on a local system successfully and have that synced to the container.
2. Navigate to the System Report
3. See that the System Report gets a green checkmark for having GD or ImageMagick, even though GD is now required.
