minor updates (rustyline 12 → 13, time update for Rust 1.80) and license clarification

[decathorpe]

I'm working through some cleanups in the packages for Rust applications we have in Fedora Linux and have another small PR :)

• deps: update rustyline to v13

While version 14 is the latest, most popular dependent crates still seem to depend on v13.

• deps: update time in the lockfile to avoid issues with Rust 1.80

Rust 1.80 added some From<T> implementation for Box<_> that made older versions of the time crate fail to compile. Bumping the version of the time crate in the lockfile resolves this issue.

• meta: clarify license as GPL-2.0-only

The GPL-2.0 SPDX identifier is deprecated since SPDX license list version 3.0:
https://spdx.org/licenses/#deprecated

I'm assuming that GPL-2.0 was intended to mean GPL-2.0-only (otherwise the deprecated form should have been GPL-2.0+ for GPL-2.0-or-later).
