Provide a [TlsConfig] for [ureq].

This is used by Nushell's networking commands (http) to handle secure (or optionally insecure) HTTP connections. The returned connector enables ureq to perform HTTPS requests. If allow_insecure is set to true, certificate verification is disabled.

This function is only available when the network feature is enabled, and requires exactly one of the native-tls or rustls-tls features to be active.

With native-tls

When built with native-tls, this uses the platform TLS backend:

• OpenSSL on most Unix systems
• SChannel on Windows

These are mature and widely-deployed TLS implementations. Expect strong platform integration.

With rustls-tls

When built with rustls-tls, this uses the pure-Rust [rustls] library for TLS. This has several benefits:

• Easier cross-compilation (no need for OpenSSL headers or linker setup)
• Works with musl targets out of the box
• Can be compiled to WASM

A [NuCryptoProvider] must be configured before calling this function. Use CRYPTO_PROVIDER.default() or CRYPTO_PROVIDER.set(...) to initialize it.
