Add OSSF Scorecard security workflow

I tested this project using [OSSF Scorecard](https://securityscorecards.dev/) by the [Open Source Security Foundation](https://openssf.org/). Their aim is:

> We created Scorecard to help open source maintainers improve their security best practices and to help open source consumers judge whether their dependencies are safe.

> Scorecard is an automated tool that assesses a number of important heuristics ("checks") associated with software security and assigns each check a score of 0-10. You can use these scores to understand specific areas to improve in order to strengthen the security posture of your project. You can also assess the risks that dependencies introduce, and make informed decisions about accepting these risks, evaluating alternative solutions, or working with the maintainers to make improvements.

**Unfortunately, this project only received a value of 5.7/10**

Please follow these steps to add the Action to the codescanning suite to ensure this project continues to stays safe
