Use CHANGELOG to populate release notes

[stevehipwell]

Support setting the release notes from a CHANGELOG.md file following the Keep a Changelog format. My suggestion would be to add a --release-notes-source flag to allow the current behaviour to be modified.

It would be nice also if the changelog could be read from 'artifacthub.io/changes' annotations, such that to use a single place to release notes for GitHub and Artifact hub

@tuxerrante I'd suggest it'd be better if the annotations could be populated either from the commits (current functionality) or CHANGELOG.md (requested functionality). I currently do this manually as I need to strip out the markdown formatting.

For me generate-release-notes: true and make-release-latest: false didn't work.
I still get 'latest production-ready' releases and no extra info.
I'm using a ct.yaml like this

remote: origin
target-branch: main
chart-dirs:
  - charts
chart-repos:
  - kapparmor=https://tuxerrante.github.io/kapparmor/
helm-extra-args: --timeout 600s
generate-release-notes: true
make-release-latest: false

And a job like this (still work in progress)

  release-chart:
    needs: ['build-app']
    if: github.ref_name == 'main' || github.event_name == 'pull_request' || startsWith(github.event.ref, 'refs/tags/v')
    permissions:
      contents: write
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v3
        with:
          fetch-depth: 0

      - name: Configure Git
        run: |
          git config user.name "$GITHUB_ACTOR"
          git config user.email "$GITHUB_ACTOR@users.noreply.github.com"

      - name: Install Helm
        uses: azure/setup-helm@v3

      - uses: actions/setup-python@v4
        with:
          python-version: '3.9'
          check-latest: true

      - name: Set up chart-testing
        uses: helm/chart-testing-action@v2.3.1

      - name: Run chart-testing (list-changed)
        id: list-changed
        run: |
          changed=$(ct list-changed --target-branch ${{ github.event.repository.default_branch }})
          if [[ -n "$changed" ]]; then
            echo "::set-output name=changed::true"
          fi

      - name: Run chart-testing (lint)
        run: ct lint --target-branch ${{ github.event.repository.default_branch }}

      - name: Create kind cluster
        uses: helm/kind-action@v1.4.0
        if: steps.list-changed.outputs.changed == 'true'

      - name: Run chart-testing (install)
        run: ct install --print-config --target-branch ${{ github.event.repository.default_branch }}

      - name: Run chart-releaser
        uses: helm/chart-releaser-action@v1.5.0
        env:
          CR_TOKEN: "${{ env.GITHUB_TOKEN }}"
