Create a Security Policy

[mirabtellegen]

Hi team, I've noticed that there is not a security policy for this project. Security policies can be important for safe and timely vulnerability reporting, and I've noticed some outdated dependencies here and in shoutem.github.io as well. I'm raising this issue to suggest you define a policy for this project.

You could use GitHub's private vulnerability reporting feature here or define other ways for users to reach out in the Security tab associated with the repo!
