The placeholders in the extension descriptor file(s) looks like: `<%= value-to-be-replaced %>`. When used outside Jenkins the secret which corresponds to `id-of-a-credential-in-jenkins` needs to be provided as environment variable in screaming snake case, e.g.: `export ID_OF_A_CREDENTIAL_IN_JENKINS=<secret>`. `id-of-a-credential-in-jenkins` needs to be provided in a way so that it can be translated into a valid environment variable name (e.g. don't start with a number). `value-to-be-replaced` must match this regex: `^[-_A-Za-z0-9]+$`."
