feat(jobs): Pass PROVIDERS_URL and PROVIDERS_RELOAD_INTERVAL to runners

[nalanj]

Describe your changes

Sets up needed ENV vars for providers reloading to render runner and local runner.

@TBonnin No env vars were set in RemoteRunner, but it wasn't completely clear to me how RemoteRunner works at this point. I may need help figuring out how it works.

NAN-2105 Dynamically reload `providers.yaml`

[TBonnin]

Remote runner is for Enterprise customer who are running Nango in their own infrastructure. In this case we don't control where the runner(s) are.
We should document this env var in case Enterprise customers want to also use the dynamic url (@khaliqgant do we have an Enterprise setup guide somewhere?) but we should also make sure that the providers data is loaded from binary if this env var is not specified. In a single tenant enterprise setup, dynamic loading of providers isn't bringing much value anyway
