pipeline: outputs: administration: document oauth2.client_secret_file

Add the `oauth2.client_secret_file` parameter to the OAuth 2.0 tables in the
HTTP and OpenTelemetry output plugins, and to the shared OAuth 2.0 parameter
table in the YAML pipeline section. The parameter takes a path to a file
containing the client secret and overrides `oauth2.client_secret` when both
are set.
