reqwest improvements: upgrade to version 0.12, disable default feat…

…ures, support TLS control

* Update dependencies in Cargo.toml to disable default features for reqwest and add new feature flags for OpenSSL and Rustls. This enhances control over the used TLS implementation.

* Upgrade reqwest dependency to version 0.12

- fix tests
- update test assertions for IP details to reflect new expected values for city, region, location, postal code, and timezone.

* Update Cargo.toml

adding these
```
default = ["default-tls"]
default-tls = ["reqwest/default-tls"]
native-tls = ["reqwest/native-tls"]
rustls-tls = ["reqwest/rustls-tls"]
```

as suggested by @max-ipinfo in #60 (comment)

* Refactor HTTP request formatting in IpInfo implementation

- Fixes `the borrowed expression implements the required traits`
- Changed string formatting from `format!` to direct string interpolation for POST and GET requests in `ipinfo.rs`.
- This improves readability and maintains consistency in the codebase.
