dev: explore making command line parsing easier to adapt and maintain

Currently

Clj-watson employs cli-matic to specify and parse its command line options.

Cli-matic is good, but I think babashka.cli will likely be a better fit.

They both support specifying your command line, but babashka.cli is more of a toolbox than just a DSL and offers more flexibility:

Can add a flag without expressing the [no-] variant documented in usage. Something we'd like to do for #67.
It should make it simpler to restructure the current awkward [ONLY APPLIED IF USING DEPENDENCY_CHECK STRATEGY] arguments to their own section in usage help
Hiding a deprecated arg from usage help would be simple. Something we are considering: https://github.com/clj-holmes/clj-watson/issues/70#issuecomment-2264399893
And babashka.cli is very actively maintained and is happy to respond to new ideas and PRS (should we have any)

Clj-watson explicitly supports clojure tool -T usage. At the very least, we need to retain any existing -T niceties. See https://github.com/clj-holmes/clj-watson/issues/67#issuecomment-2264578457

I'll explore this idea locally, and if it all is good, follow up with a PR.
