Add security policy supporting GitHub private reporting & Bug Bounty (#…

…485)

This is an updated version of our [standard security policy](https://github.com/EmbarkStudios/.github/blob/master/SECURITY.md) to be adapted for our repositories that use GitHub's new [Private vulnerability reporting](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing/privately-reporting-a-security-vulnerability) as well as our Security Bug Bounty Program, which we now use here for cargo-deny 🎉

 ## [Unreleased] - ReleaseDate
+### Added
+- [PR#485](https://github.com/EmbarkStudios/cargo-deny/pull/485) This project and repository is now part of our Security Bug Bounty Program and has Private vulnerability reporting enabled. See [`SECURITY.md`](./SECURITY.md) for more details.

 ## [0.13.5] - 2022-11-08
 ### Fixed
 - [PR#481](https://github.com/EmbarkStudios/cargo-deny/pull/481) bumped `krates` to 0.12.5 to fix an issue where features present (and enabled) for a crate could be remove if the index entry for the crate didn't contain that feature. The features are now merged to (hopefully) more accurately reflect the features that are "truly" available according to both the index and the actual crate manifest on disk.
