Which problem is this feature request solving?

When authenticating using Github App credentials, the github source plugin currently supports only reading the key material from a file via the private_key_path configuration directive.

In scenarios like when cloudquery is run in a CI pipeline job, any key material is typically injected via environment variables so currently one needs to have a separate build step where the contents of the environment variable holding secrets are echoed into a file, so that cloudquery can then use it. This works but is cumbersome.

Describe the solution you'd like

I'd like to have a configuration directive private_key that lets me supply the private key as a string, for instance from an environment variable. This would be mutually exclusive with private_key_path to avoid confusion about what key material is being used.
