@googleapis/runtimeconfig submodule is not available from npm

[DimuDesigns]

I tried to install the @googleapis/runtimeconfig submodule as instructed by the link below:

https://github.com/googleapis/google-api-nodejs-client/tree/main/src/apis/runtimeconfig

But the package is not present on NPM.

I checked the @google-cloud nodejs client libraries as well but the Runtime Configurator API is not supported there either.

Please make it available on NPM.
