pass in all configured experiments

[jakecoffman]

Works with:

• add support for experiments dependabot/proxy#221

This makes it easier to use experiments in the Proxy. We add the experiments from the job to the JSON file we give to the Proxy as input. It doesn't require an additional PR to add the experiment as an environment variable.

Also this graduates the Proxy caching experiment to always be on. It has been enabled since January 2024.

• ProxyBuilder.run expects jobToken before dependabotApiUrl, but these values are reversed. This starts the integration proxy with the URL as JOB_TOKEN and xxxyyyzzzz as DEPENDABOT_API_URL; swap them so the test exercises a valid proxy configuration.
