The latest stable release of sled indirectly depends on an unmaintained crate (instant)

[VorpalBlade]

Bug reports must include all following items:

1. expected result: No cargo deny warnings when using the non-alpha release of sled
2. actual result:

When using cargo deny on my project that has an indirect dependency on sled I get:

error[unmaintained]: `instant` is unmaintained

    ├ This crate is no longer maintained, and the author recommends using the maintained [`web-time`] crate instead.

This can be fxed by a new release in the sled 0.34.x series that depends on a newer semver version of parking_lot (0.12.x). As 1.0 alpha has apparently been in alpha for over a year, that does not seem like a viable short term fix to this.

1. sled version: 0.34.7
2. rustc version: 1.82.0
3. operating system: Arch Linux
4. minimal code sample that helps to reproduce the issue: N/A
5. logs, panic messages, stack traces: N/A
