Bump minimal versions of range dependencies

[davidhewitt]

As a follow up to #4604, it's probably time to go through our range dependencies in the Cargo.toml and bump these a bit. e.g. hashbrown 0.9 is about 4 years old, and barely downloaded. It looks like hashbrown 0.11 is where the download counts pick up, so I think we can bump to there for sure. MSRV works with 0.14, so we could even go higher.

Labelling as good first issue, I think this would be a nice cleanup to land in 0.23 if someone is interested.

Range dependencies in Cargo.toml:

• hashbrown (to 0.11 or maybe even 0.14)
• chrono-tz (needs analysis)
• eyre (needs analysis)
• indexmap (needs analysis)
• num-complex (needs analysis)
