Can't filter containers in spinach.yaml for deployments

[1stewart]

Describe the bug
Can't filter containers in spinach.yaml for deployments. Filtering by deployment FQN or code works as expected.

To Reproduce

1. Have a report with a deployment warning for no resources/limits on a container

2. Create a spinach.yaml file with the following content

popeye:
  excludes:
    apps/v1/deployments:
      - name: linkerd/linkerd-controller
        codes:
          - 106

3. Run with the spinach.yaml passed in .\popeye.exe --save --out html -l warn -f .\spinach.yaml

As expected, the warn isn't there

4. Create a spinach.yaml file with the following content (adding the container)

popeye:
  excludes:
    apps/v1/deployments:
      - name: linkerd/linkerd-controller
        containers:
          - public-api
        codes:
          - 106

5. Run with the spinach.yaml passed in .\popeye.exe --save --out html -l warn -f .\spinach.yaml

6. Container isn't picked up by configuration, fails back to showing non-matched deployment

Expected behavior
(I think) it should allow filtering to containers, unless this is a limitation of the deployments API and the way they're referenced in its spec.

kubectl get deployment -n linkerd linkerd-controller -o yaml
apiVersion: apps/v1
kind: Deployment
metadata:
...
  name: linkerd-controller
  namespace: linkerd
...
spec:
...
  template:
...
    spec:
      containers:
      - args:
        - public-api
...
...
        name: public-api

Versions (please complete the following information):

• OS: Windows 10
• Popeye: 0.9.7 (also on 0.9.0)
• K8s 1.20.0

Additional context
Ideally we don't want to filter the whole deployment or popeye code, as any other containers would require limits/requests

Can confirm that this only seems to allow filtering of error codes for specific containers when used under excludes.v1/pods

Have attempted to use the pattern described by the OP to filter error codes under specific containers for daemonsets, deployments and statefulsets and this does not work.
