<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Docs: Correct the suggested alternative for the deprecated `wp_cache_reset()` function.
While this was previously added and reverted more than once as part of various documentation cleanup efforts, `wp_cache_switch_to_blog()` appears to be the correct alternative for `wp_cache_reset()`, per the latter's DocBlock.
This commit also corrects the `@deprecated` tag for `WP_Object_Cache::reset()` to link to the `::switch_to_blog()` method of the class, instead of the function of the same name.
