feat: custom resource config for teams

[srodenhuis]

This PR offers the ability (if required) to adjust the resource configuration of Tekton Tasks, Grafana, Tekton Dashboard and Alertmanager. Summary:

• no resource defaults in teamConfig
• no changes in apl-api
• platform-admin can add resource customizations directly in values repo
• only for edge cases where the defaults are not sufficient

Adjustments can be made by adding:

teamConfig:
    demo:
        resources:
            alertmanager:
                enabled: true
                resources:
                    limits:
                        cpu: "5"
                        memory: 5Gi
                    requests:
                        cpu: 5m
                        memory: 5Mi

One question about the defaults.
The testing worked. Could change the resources through the values for for team apps and tekton tasks ✅

[CasLubbers]

Do we maybe want to set these defaults lower? I think its pretty high for a simple git-clone task

[srodenhuis]

No because we want to provide a good initial user experience
