Allows reusable workflow builder refs to be specified as a 40-character commit SHA (e.g. abc123...) in addition to semver tag refs. At verification time the SHA is resolved to its associated release tag(s) via the GitHub REST API, and at least one must be a valid vX.Y.Z semver tag. Introduces TagResolver interface and GitHubTagResolver implementation. Set GITHUB_TOKEN to authenticate API requests and avoid rate limiting. Fixes slsa-framework#12 Signed-off-by: James Carnegie <james.carnegie@datadoghq.com>

Resolves #12
Summary
SHA pinning is immutable: once committed, a SHA cannot change, making it a stronger security guarantee than mutable tags.
