Function get_rank_info

pub async fn get_rank_info(
    client: &Client,
    region_str: &str,
    summoner_id: &str,
    riot_api_key: &str,
) -> Result<Vec<HashMap<String, Value>>, Box<dyn Error + Send + Sync>>

⚙️ Function: Fetches ranked information for a player using their summoner ID.

This function sends a request to the Riot API to retrieve ranked information for a player, including their rank, division, league points (LP), wins, and losses in different game modes (e.g., Solo/Duo, Flex).

Parameters:

• client: An instance of the reqwest::Client used to send HTTP requests.
• region_str: A string representing the region (e.g., euw1, na1, kr) where the player’s account is located.
• summoner_id: The unique summoner ID of the player, used to identify them in the ranked ladder.
• riot_api_key: The API key used to authenticate the request with the Riot API.

Returns:

• Result<Vec<HashMap<String, Value>>, Error>: A vector of HashMap objects containing ranked information for each game mode (Solo/Duo, Flex) or an error if the request fails.

⚠️ Notes:

• The returned ranked information includes game modes like Solo/Duo and Flex, along with details such as tier, rank, LP, wins, and losses.
• The function returns an empty vector if no ranked data is found for the player in the specified region.

Example:

let rank_info = get_rank_info(&client, "euw1", "abcdef1234567890abcdef1234567890", riot_api_key).await?;

The resulting rank_info will contain ranked data for different game modes, such as:

[
  {
    "queueType": "RANKED_SOLO_5x5",
    "tier": "Gold",
    "rank": "IV",
    "leaguePoints": 50,
    "wins": 30,
    "losses": 20
  },
  {
    "queueType": "RANKED_FLEX_SR",
    "tier": "Silver",
    "rank": "II",
    "leaguePoints": 75,
    "wins": 15,
    "losses": 10
  }
