Remove deprecation Warning on sanitize_url()

[Ipstenu]

Bug Description

The use of sanitize_url() is still listed as deprecated, however as of WordPress 5.9 it has been un deprecated

Minimal Code Snippet

Use sanitize_url() in a line of code.
ERROR sanitize_url() has been deprecated since WordPress version 2.8.0. Use esc_url_raw() instead.
(WordPress.WP.DeprecatedFunctions.sanitize_urlFound)

This can be fixed by removing it from the deprecation list.

Tested Against develop branch?

I have not tested against develop, but I did check here:

https://github.com/WordPress/WordPress-Coding-Standards/blob/develop/WordPress/Sniffs/WP/DeprecatedFunctionsSniff.php#L412

So it's still on the sniffs :)

@Ipstenu Thanks for reporting this. The deprecation lists haven't been updated for WP 5.9 yet.

As of WordPress 6.1, sanitize_url() becomes the recommended function for sanitizing a URL, see #WP55852 for details.

I think it should be removed from the deprecated functions sniff (as noted above) and added to the list of sanitizing functions.

@SergeyBiryukov It definitely will be removed when we run the deprecated code scanner before releasing the next version.
