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.

Follow-up to [13066], [21403], [22111], [33678], [34225], [34226], [40929].
