[org.jenkins-ci.plugins:gitlab-plugin] Jenkins GitLab Plugin potentially allows attackers to use statistical methods to obtain valid webhook token

Jenkins GitLab Plugin 1.5.35 and earlier uses a non-constant time comparison function when checking whether the provided and expected webhook token are equal, potentially allowing attackers to use statistical methods to obtain a valid webhook token. GitLab Plugin 1.5.36 uses a constant-time comparison when validating the webhook token.
