feat: ability to provide specific config.driver for msnodesqlv8

[alexsch01]

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

• while maintaining compatibility with configs with driver value "msnodesqlv8"
• if config.driver is a truthy value and not equal to "msnodesqlv8", it will use that specific driver

---

Changed README, don't know if GitHub Pages site needs an update

---

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: "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);
  }
})();

@dhensby let me know if you are ok with this feature

In CI - before running mssql with msnodesqlv8, I run a script that patches this package to use the "ODBC Driver 18 for SQL Server" driver

Thanks @alexsch01 - my main concern now is that this doesn't have any test coverage, so there's no regression detection for the futue. Would you be able to add a test to show that we can update the config with a different driver and it still works?

[alexsch01]

@dhensby I added a test, can you let the checks run?

The last 2 commits will fail commit linting - they can be squashed into the first commit

[alexsch01]

@dhensby hey can you let checks run?

[alexsch01]

one more time, sorry @dhensby

[alexsch01]

All tests passed! @dhensby

Thanks so much for the work on this and putting up with the tedium of the commit conventions!
