feat(forge): add flag to disable HTTPS certificate validation for RPC

[mirokuratczyk]

Motivation

Resolve #11907 (comment).

Solution

• Add --insecure/-k flag to forge script which toggles ignoring invalid certs (e.g., self-signed)

I'm not sure this PR handles all possible codepaths as new providers are built in many different places and each needs to be configured with .accept_invalid_certs(bool).

PR Checklist

• Added Tests
• Added Documentation
• Breaking changes

Nice, but I guess it would be actually cleaner to build the provider using :

foundry/crates/cli/src/utils/mod.rs

Lines 102 to 106 in c646b88

	/// Returns a [RetryProvider] instantiated using [Config]'s
	/// RPC
	pub fn get_provider(config: &Config) -> Result<RetryProvider> {
	get_provider_builder(config)?.build()
	}

this would retrieve eth_rpc_accept_invalid_certs key from the config directly.

This actually confirms the need for a refactor of the RpcOpts/EvmArgs common fields. So I'll open a dedicated issue to get feedback from the project team.

I pushed an update that uses get_provider as suggested. Seems to be working with --insecure.

Sounds like we'll wait for #11964 to be merged first though and go from there.
