Introduce first test for browser-side behavior.

[ghemawat]

Added a test that uses chromedp to drive web page interactions and check the resulting display.

Caveat: just adding a single test initially (it checks sorting of the "Top" view table). Other tests will be added later.

Caveat: coverage of browser Javascript is not gathered, so we won't be able to rely on coverage to measure quality/changes in Javascript testing.

Will merge once tests complete.

I sync-ed with other changes, dropped the unnecessary action to setup chrome (it is already available by default in github runners), and dropped the "-v" from the "go test" invocation.

This should now be fine to merge.
