docs: Fix typo in std/src/thready/scoped.rs

Fix typo in std/src/thread/scoped.rs

Why this pr

This PR fixes the typo mentioned in #155275.

I know this was originally fixed in #155325 and then in #155328.

But since the first issue was closed due to some ai slop and the second one was closed because the first one was already opened, it seems to me that this PR is still needed.

What this pr does

This PR "just" fixes a typo inside the std/src/thread/scoped.rs file

Changing the comment from this:

/// borrow non-`'static` data from the outside the scope. See [`scope`] for
/// details.

to this:

/// borrow non-`'static` data from outside the scope. See [`scope`] for
/// details.
