Modified path for random_agent file in readme

[championballer]

Description

IMO It would be better to have the exact path of the example file for random agent rather than a reference to examples/

Motivation and Context

Had just started exploring the repo. Took me a separate search to find the file, which won't be required if the exact path was mentioned. We could even create a link to the file if the modified version seems bloated.

Thought the suggestion was too small to file an issue.

How Has This Been Tested?

README change. No test should be needed.

Looks like CI is broken due to 6 hlint warnings (should probably be turned off).
