Rollup merge of #102313 - anirudh24seven:update_sleep_ms_doc, r=Mark-Simulacrum

Update docs so that deprecated method points to relevant method

The docs for the deprecated 'park_timeout_ms' method suggests that the user 'use park_timeout' method instead (at https://doc.rust-lang.org/std/thread/index.html).

Making a similar change so that the docs for the deprecated `sleep_ms` method suggest that the user `use sleep` method instead.
