chore(gastby-transformer-sqip): Use createContentDigest helper (#18534)

* chore(gastby-transformer-sqip): Use createContentDigest helper Updates the plugin to use the help instead of manually handling the crypto work. * chore(gatsby-transformer-sqip): Remove unnecessary await keyword The `await` keyword was causing Jest to issue a warning because `describe` functions shouldn't be returning Promises.
