Upgrade Axum to 0.7, tower to 0.5, opentelemetry to 0.23, and hyper to 1.0 (#183)

* refactor(deps): Upgrade deps to support axum 0.7, tower 0.5, opentelemetry 0.23, and hyper 1.0

* style: Run rustfmt on code changes

* build: Upgrade minimum rust version to 1.75, required by the updated zip library

* build: Fix a few more lints
- Allow unused for HeaderValue
- Use identity function in map
- Dont use default for unit struct
- Fix doc indents
- tokio-unstable config

* build: fix warnings and allow mpl for webpki-roots

* refactor: Cleanup differences between axum::http::StatusCode and http::StatusCode

* refactor(deps): Upgrade dependency versions for reqwest, reqwest middleware, reqwest retry, reqwest telemetry, etc
