Re-enable web benchmarks

[guidezpl]

It seems Chrome 89 brought a change that causes the benchmarks to fail. To enable development, they've been disabled.

Hey @pennzht could you take a look? Benchmarks aren't currently running

Hi @guidezpl , I have made pr here to add the changes introduced, but this pr requires knowledge of setting up the tests from basics, which I don't know . I would be more than happy to read something to get started on writing tests.

Oh nice, thanks. I don't have any more specific knowledge for testing than the guides on the Dart and Flutter docs sites. I'm not aware of browser testing that is version specific, do you have more info @yjbanov?

@ditman and @amanv8060 just fixed package:web_benchmarks. @ditman will attempt to reenable the gallery benchmark now.

Here's the PR reenabling the web benchmarks: #604

I hope it helps. Thanks to @amanv8060 for the initial fix to web_benchmarks!
