"az functionapp config set --use-32bit-worker-process" is not applying changes since v2.60.0

### Describe the bug

I am unable to update a function app to use 64 bit, when using version 2.60.0. This was working correctly in 2.59.0 and 2.54.0.
Conversely, if the function app is already configured to use 64 bit, I cannot switch it to use 32 bit.

For example:

PS>az functionapp config show --name my-functionapp --resource-group my-resource-group --query "use32BitWorkerProcess"
true

PS> az functionapp config set --name my-functionapp --resource-group my-resource-group --use-32bit-worker-process false
{
...
"use32BitWorkerProcess": true,
...
}

PS>az functionapp config show --name my-functionapp --resource-group my-resource-group --query "use32BitWorkerProcess"
true
