[CodeHealth][rust] Update futures 0.3.27 => 0.3.31 (#27707)

* [CodeHealth][rust] Update `futures` `0.3.27` => `0.3.31`

This PR updates the `futures` crate to `0.3.31`. This crate was causing
audit failures on a different PR updating `chrono`.

This change removes the previous `extra_src_roots` instructions for the
future deps, as those started panicking when running `gnrt` in the
current version.

`chrono` PR: #27693

Resolves brave/brave-browser#44057
