ci(helm): migrated charts to this repository instead

[bosbaber]

In order to streamline the development process, and making it easier to verify if developers remembered to update the helm charts, we are now migrating the relevant helm charts to the testnet mono repository. This will allow us to use LLM and other tools to detect problems introduced earlier in the development life cycle.

This PR migrates the helm charts to here, and introduces pipelines to facilitate testing and publishing of the charts using Github Pages.

Pull request overview

This PR migrates the Boutique and TestNet Wallet Helm charts into the interledger/testnet monorepo and adds GitHub Actions workflows to validate charts on PRs and publish packaged charts to the charts branch (GitHub Pages) on releases.

Changes:

• Adds helm-unittest suites to validate services, deployments, configmaps, and secrets behavior.
• Introduces CI workflows for chart linting/testing/rendering on PRs and chart packaging/index publishing on release.

helm/boutique/tests/deployment.frontend_test.yaml:46

• The frontend ConfigMap test expectations don’t match helm/boutique/values.yaml: the chart sets API_BASE_URL from config.frontend.apiBaseUrl (default https://boutique.example.com) and does not define a PORT key for the frontend ConfigMap. This test will fail against the current chart.

  - it: 'should create configmap with correct environment variables'
    template: configMap.frontend.yaml
    asserts:
      - equal:
          path: metadata.name
          value: test-rafiki-boutique-frontend
      - equal:
          path: data.API_BASE_URL
          value: "https://boutique.example.com"
