Add create-basis/process example to tools.build docs

[seancorfield]

Per discussion on Slack about using clojure.tools.build to run tests that need a particular classpath, including the test runner itself, Alex said "you can use a combo of create-basis, java-command, and process to execute it".

It would be great if the tools.build guide had an example of doing this with Cognitect's test-runner to provide a canonical example of how to do this in a build script (where the build script is invoked as the only dependency via -T).

This is well-documented on https://clojure-doc.org so I'm closing this output.

I would like to leave this open for consideration in the tools.build guide, thanks

Fair enough. The relevant section on clojure-doc.org is https://clojure-doc.org/articles/cookbooks/cli_build_projects/#running-tasks-based-on-aliases -- feel free to lift any parts of them for inclusion in the tools.build guide.
