Docs: Correct the wording in wp_lostpassword_url() description.

This affects:
* The `wp_lostpassword_url()` function.
* The `lost_password_html_link` filter.

The filter description was copied from the function, which appears to be not quite accurate, as the lost password can only be reset, not retrieved.

Follow-up to [11448], [54206].

See #55646.
