wp_title() doc appears broken

[smileBeda]

Issue Description

This documentation appears broken. There should be at least some $args description, source code...

URL of the Page with the Issue

https://developer.wordpress.org/reference/functions/wp_title/

Why is this a problem?

It is unclear what that function even is, when there is no context.

Suggested Fix

• I checked the code, the docbloc is there, technically this should be automatically generated by the parser... if that for some reason is not working, below attache the information to add
• I believe there usually also is source code section

/**
 * Displays or retrieves page title for all areas of blog.
 *
 * By default, the page title will display the separator before the page title,
 * so that the blog title will be before the page title. This is not good for
 * title display, since the blog title shows up on most tabs and not what is
 * important, which is the page that the user is looking at.
 *
 * There are also SEO benefits to having the blog title after or to the 'right'
 * of the page title. However, it is mostly common sense to have the blog title
 * to the right with most browsers supporting tabs. You can achieve this by
 * using the seplocation parameter and setting the value to 'right'. This change
 * was introduced around 2.5.0, in case backward compatibility of themes is
 * important.
 *
 * @since 1.0.0
 *
 * @global WP_Locale $wp_locale WordPress date and time locale object.
 *
 * @param string $sep         Optional. How to separate the various items within the page title.
 *                            Default '»'.
 * @param bool   $display     Optional. Whether to display or retrieve title. Default true.
 * @param string $seplocation Optional. Location of the separator (either 'left' or 'right').
 * @return string|void String when `$display` is false, nothing otherwise.

There also should be a bold notice stating that this function is not suggested anymore and instead, add_theme_support should be used.
