ci: pin Microsoft.Azure.Functions.ExtensionBundle to latest stable version [backport 3.10] (#14141)

Backport c2dd2c5 from #14059 to 3.10.

The most recent [Azure Extension
Bundle](https://learn.microsoft.com/en-us/azure/azure-functions/extension-bundles)
release,
[4.23.1](https://github.com/Azure/azure-functions-extension-bundles/releases/tag/4.23.1),
introduced a breaking change (see below). Currently, the Azure Functions
tests use the latest available version of this bundle between version 4
and 5 so this new version was picked up automatically. This PR pins the
Azure Extension Bundle to the most recent stable version, `4.22.0` in
addition to removing some other unnecessary configuration in
`host.json`.

Alternatively we can upgrade to the latest version of [Azure Functions
Core Tools](https://github.com/Azure/azure-functions-core-tools) since I
believe that version is compatible with the most recent release of the
Azure Extension Bundle. But it is a more involved change to update the
test runner image.
