FI-3188: Update documentation on cli_context options.

[arscan]

Summary

Updates docs to remove redundant example that is also bad ruby. I believe we had already gotten the bad ruby example fixed on the framework site but didn't get it fixed here.

Also, figured we might as well include the exampleURL flag as an example because that was the one I actually wanted to use when i was looking at this documentation.

Testing Guidance

I suppose you could regenerate the docs as explained in the readme. Also, I haven't tried out that example url flag technically, but grabbed it from the wrapper UI config so it should work.

The first example should be valid - that's how we use it in g10 ( https://github.com/onc-healthit/onc-certification-g10-test-kit/blob/7442075988e9ccf86046669a114234abc682790c/lib/onc_certification_g10_test_kit.rb#L92 ) and the EOM test kit ( https://github.com/inferno-framework/eom-test-kit/blob/83e184dd7109a4277c0a7128310eb647ba9f7868/lib/eom_test_kit/eom_test_suite.rb#L46 )
We have some custom code in the DSL to allow arbitrary keys in the cli_context block:

inferno-core/lib/inferno/dsl/fhir_resource_validation.rb

Line 322 in 3ceecba

class CliContext

Ah, great point @dehall! I completely missed that. I do think that it would be a good idea to just call out the difference in the examples there, so I updated it. Also, I think it would still be a good idea to include that exampleUrl param, as I was looking for that anyhow.

Also, I assumed that this was a problem that was fixed in inferno-framework docs site, but turns out that was something similar but unrelated. I was just in the wrong mindset here.
