attempt to fix tests

[davidsiaw]

This PR attempts to fix the tests to get them to a working state again.

Changes are:

• comply with new capybara driver syntax
• remove webdriver gem interfering with chrome download
• add required async-io gem (probably should be pulled in by falcon?)
• update ruby min version and removed other gem version restrictions.

Types of Changes

• Maintenance.

Contribution

• I added tests for my changes.
• I tested my changes locally.
• I agree to the Developer's Certificate of Origin 1.1.

async-io is deprecated and should be replaced by io-endpoint - not sure how much we need to fix here.

[davidsiaw]

OK I switched async-io out to io-endpoint and it seems to work...? I hope you will forgive me if I seem to be guessing here. I don't know how a lot of this hangs together.

[davidsiaw]

upon closer inspection, it seems its only being pulled in but not actually used, so I just got rid of it.

[ioquatix]

Yes, I just checked it, and I think removal is fine.

[davidsiaw]

So it seems we JRuby doesn't like io-event, and TruffleRuby's Fiber has not added your change to implement a different scheduler. Not sure why this shows the checks are unsuccessful when it is marked as experimental.

Unfortunately there is a multi-year discussion about that: https://github.com/orgs/community/discussions/15452 and actions/runner#2347 - not sure this will get resolved any time soon, but it's okay and expected.
