fix: use WARNING log level for chrome driver to capture console.warn

'SEVERE' only captured console.error, missing console.warn calls.
The 'did you mean to say Foo()' message uses console.warn (WARNING level).
'WARNING' captures WARNING + SEVERE but excludes INFO (console.log),
so initialization spam that broke the 'no spurious warnings' test is
still filtered out.
