Change ACA containerPort parameter to int instead of string

[eerhardt]

Today when we allocate the container port parameter for ACA apps we are using the default typeof(string)

aspire/src/Aspire.Hosting.Azure.AppContainers/ContainerAppContext.cs

Lines 706 to 731 in 1994993

	private BicepValue<int> AllocateContainerPortParameter()
	=> AllocateParameter(ResourceExpression.GetContainerPortExpression(resource));
	private void AllocateContainerRegistryParameters()
	{
	_containerRegistryUrlParameter ??= AllocateParameter(_containerAppEnvironmentContext.Environment.ContainerRegistryUrl);
	_containerRegistryManagedIdentityIdParameter ??= AllocateParameter(_containerAppEnvironmentContext.Environment.ContainerRegistryManagedIdentityId);
	}
	private ProvisioningParameter AllocateParameter(IManifestExpressionProvider parameter, Type? type = null, SecretType secretType = SecretType.None)
	{
	if (!_allocatedParameters.TryGetValue(parameter, out var parameterName))
	{
	parameterName = parameter.ValueExpression.Replace("{", "").Replace("}", "").Replace(".", "_").Replace("-", "_").ToLowerInvariant();
	if (parameterName[0] == '_')
	{
	parameterName = parameterName[1..];
	}
	_allocatedParameters[parameter] = parameterName;
	}
	if (!_provisioningParameters.TryGetValue(parameterName, out var provisioningParameter))
	{
	_provisioningParameters[parameterName] = provisioningParameter = new ProvisioningParameter(parameterName, type ?? typeof(string)) { IsSecure = secretType != SecretType.None };

Instead, this should be typeof(int).

This also seems to affect the probes port, the generated bicep fails when trying to deploy.

      app.Template.Containers[0]
        .Value!.Probes.Add(
          new ContainerAppProbe
          {
            ProbeType = ContainerAppProbeType.Startup,
            HttpGet = new ContainerAppHttpRequestInfo
            {
              Path = "/alive",
              Port = app.Configuration.Ingress.TargetPort,
            },
            InitialDelaySeconds = 5,
            PeriodSeconds = 10,
            FailureThreshold = 10,
          }
        );

It generates

      containers: [
        {
          probes: [
            {
              failureThreshold: 10
              httpGet: {
                path: '/alive'
                port: biohelp_api_containerport // Error here
              }
              initialDelaySeconds: 5
              periodSeconds: 10
              type: 'Startup'
            }
