chore: fix minimal-versions correctness (tokio-rs#2246)

## Motivation

Fix minimal-versions failure.

## Solution

Upgrade all the dependencies to their most recent semver-compatible
version, adjusting back down as necessary for MSRV.

Essentially a cherry-pick of tokio-rs#2231, but redone by hand.

## Tests

- `cargo minimal-versions msrv verify -- cargo check --all-features`
- `cargo minimal-versions msrv verify -- cargo check --no-default-features`

## Methodology

- `cargo update && cargo upgrade --to-lockfile`
  - Identify [a bug](killercup/cargo-edit#750) and manually resolve it
- loop; upgrade transitive deps
  - `cargo minimal-versions check --all-features`
  - Identify failing dep
  - `cargo minimal-versions tree -i dep --all-features`
  - Find the closest dependency leading to pulling in `dep`
  - `cargo add fixdep --optional` to force a more recent more-minimal-versions-correct version
- loop; downgrade to msrv
  - `cargo minimal-versions msrv verify -- cargo check --all-features`
  - Identify failing dep
  - `cargo minimal-versions tree -i dep --all-features`
  - Find the version that supports MSRV from lib.rs
  - `cargo upgrade dep@msrv`
