Bump min version of swift-nio-extras (#2101)

Motivation:

We require that the ServerQuiescingHelper is Sendable, which it is as of
version 1.12.0, however our depenencies our depenency requirements don't
express that and if an older version is resolved then compilation will
fail.

Modifications:

- Bump the required version to 1.24.0

Result:

More accurate version requirement
