allow usage of HttpEndpoint for urls

[pyramation]

Telescope and CosmJS support HttpEndpoint which allows users to pass headers into requests, cosmos-kit should support this. Perhaps we just need to make a modified version of chain-registry/types to allow for this

export interface HttpEndpoint {
  /**
   * The URL of the HTTP endpoint.
   *
   * For POST APIs like Tendermint RPC in CosmJS,
   * this is without the method specific paths (e.g. https://cosmoshub-4--rpc--full.datahub.figment.io/)
   */
  readonly url: string;
  /**
   * HTTP headers that are sent with every request, such as authorization information.
   */
  readonly headers: Record<string, string>;
}
