It doesn't look like there are any provided macOS 10.14 runners left so
CI never fully completes. 10.15 is also being depreciated on 5/31/2022
(in two days at the time of writing), so there is little reason to
update to that.

Although there are benefits to testing EventMachine with these older OS
versions—especially given EventMachine's legacy status and the types of
projects which are most likely to depend on it—there are also
significant costs to maintaining CI for them once GitHub Actions has
dropped support.

Under the presumption that MacOS is primarily used for development and
not for deployment, I've switched the macos GitHub Actions runners to
use the "latest" release version for ruby >= 2.6.  Earlier ruby's don't
support arm64, so they are using the macos-13 runner (which is amd64).

On the one hand, this is less explicit and is no longer "pinned", so it
may result in CI failing when GitHub Actions updates these runners.  On
the other hand, we also won't need another PR to update these every time
an old version is dropped or a new version is added.

I attempted to make the same change from windows-2019 to windows-latest.
But I saw three tests that reliably pass under windows-2019 and reliably
fail under windows-2022.  Since I don't have a Windows OS dev env at my
disposal, I'm opting to just let windows CI continue under windows-2019,
for now.

They're disabling the macOS 10.15 runner:
