feat: ability to provide config.msnodesqlv8_Driver

[alexsch01]

Being able to override CONNECTION_DRIVER (now DEFAULT_CONNECTION_DRIVER) variable for mssql/msnodesqlv8

const sql = require('mssql/msnodesqlv8');

const config = {
  server: "MyServer",
  database: "MyDatabase",
  options: {
    trustedConnection: true, // Set to true if using Windows Authentication
    trustServerCertificate: true, // Set to true if using self-signed certificates
  },
  driver: "msnodesqlv8", // Required if using Windows Authentication
  msnodesqlv8_Driver: "ODBC Driver 18 for SQL Server",
};

(async () => {
  try {
    await sql.connect(config);
    const result = await sql.query`select TOP 10 * from MyTable`;
    console.dir(result);
  } catch (err) {
    console.error(err);
  }
})();
