Suggested fix for incompatability with some plugins

Hi,

After upgrading to php 8.1, I’m seeing this error on some sites:

Fatal error: Uncaught TypeError: reset(): Argument #1 ($array) must be of type array, bool given in /site/wp-content/plugins/svg-support/functions/attachment.php:280

From what I can tell, this is caused by plugins preventing srcset functions to work. Returning false on the srcset filter was a way of disabling it completely.

I would suggest making a minor adjustment to the code to prevent a fatal error if in fact a bool is passed.

// remove srcset for svg images
function bodhi_svgs_disable_srcset( $sources ) {

	if( !is_array( $sources ) ) {
		return $sources;
	}

	$first_element = reset($sources);

Thank you in advance.
