fix: Docs example e2e test (#5456)

The docs example script was not running in CCI due to a misconfigured
test name in the ci configuration. On top of that, the test command for
e2e tests had a passWithNoTests flag, so this failed silently. Also,
there were no tests defined on the test file, as it was just a script
and the describe block was missing. And last, the test was outdated, as
it was calling a function with a wrong number of arguments and another
function that no longer existed in the token contract.

This PR fixes all of the above.
