Update Helm Charts

Our Helm charts require some version updates as well.

Before you begin

1. Install helm-docs on macOS/Linux.

Steps

1. Create a branch from main for grafana/helm-charts.

2. Update the code:

   1. Copy the content of the last CRDs into helm-charts.

      Copy the contents from agent repo production/operator/crds/ to replace the contents of helm-charts repo charts/agent-operator/crds

   2. Update references of agent-operator app version in helm-charts pointing to release version.

   3. Bump up the helm chart version.

   NOTE: Do not update the README.md manually. Running the helm-docs utility in the charts/agent-operator directory will update it automatically.

3. Open a PR, following the pattern in PR #2233.

4. Create a branch from main for grafana/agent.

5. Update the code:

   1. Update Chart.yaml with the new helm version and app version.

   2. Update CHANGELOG.md with a new section for the helm version.

   3. Run make generate-helm-docs generate-helm-tests from the repo root.

6. Open a PR, following the pattern in PR #3126.
