Support rack 3

[ioquatix]

We should probably also update CI, but we've been testing rack-attack from the rack repo (external tests) and all the tests are passing. So this should probably be good.

Closes #596

Cool, thank you!

I think to have the test pass we would additionally need to point the rack_3 appraisal to a version of actionpack that actually compatible with rack 3.

This depends on rails/rails#45741 being merged first probably.

What's blocking this from being merged?

[jeremyevans]

I think CI needs to be green for the PR before we can consider merging. No issues with the PR itself, though.

[ioquatix]

It looks like this is blocked on rails/rails#46594 and indirectly rails/rails#46206 - @rafaelfranca FYI.

I'm going to try and rework the dependencies so we don't pull in railties when testing rack 3... it might allow us to get tests passing.

From what I'm seeing, this will work if rails edge is used now that the version restriction has been relaxed here

Any updates here? Similarly blocked trying to remediate CVE-2022-30122 by upgrading to rack 3.0.

[xxswingxx]

Since rails/rails#46206 was merged, it's just rails/rails#46594 blocking this one?

[ioquatix]

Sorry, I totally forgot about this PR. I'll take a look at it in the next few days.

@ioquatix Hello, any updates on this?

[tsmartt]

Same, any update? And thanks for the library!
