/**
* Refreshes the Discord OAuth2 access token using a valid refresh token.
*
* This function makes a `POST` request to the Discord API's `/oauth2/token` endpoint
* to obtain a new access token and refresh token. It uses the `refresh_token` grant type.
*
* @param {Object} dsData - The Discord OAuth2 data required for token refresh.
* @param {string} dsData.client_id - Your application's client ID.
* @param {string} dsData.client_secret - Your application's client secret.
* @param {string} dsData.code - The original authorization code (optional but may be required by some flows).
* @param {string} dsData.refresh_token - The current valid refresh token.
* @param {string} dsData.redirect_uri - The redirect URI used in the original OAuth2 flow.
* @param {string} dsData.scope - The scope(s) to request (e.g., 'identify guilds').
*
* @returns {Promise<Record<string, any>>} Resolves with a new token object from the Discord API:
* {
* access_token: string,
* token_type: string,
* expires_in: number,
* refresh_token: string,
* scope: string
* }
*
* @throws {Record<string, any>} If the request fails, rejects with an error object containing `code` and `message`.
*
* @example
* refreshToken({
* client_id: '1234567890',
* client_secret: 'mySecret',
* code: 'optional-code',
* refresh_token: 'old-refresh-token',
* redirect_uri: 'https://myapp.com/callback',
* scope: 'identify guilds'
* })
* .then(newTokens => console.log('New Access Token:', newTokens.access_token))
* .catch(err => console.error('Failed to refresh token:', err));
