feat: add generate from latest tag

[pocesar]

This allows DETACHED HEAD tags to properly generate the RELEASE notes.
Otherwise it will always try to generate the full release notes from multiple tags

Is there a voting mechanism here? 👍 would also love this feature.

for now I've ended up using https://github.com/mikepenz/release-changelog-builder-action to generate the proper changelogs. it's a really nice action.

this is how my steps looks like if somebody just wants to copy paste it and don't spend too much time on it 😂

jobs:
    deploy:
        name: Create release

        runs-on: ubuntu-latest

        permissions:
            contents: write
            deployments: write
            pull-requests: read

        steps:
            - name: 'Build Changelog'
              id: build_changelog
              uses: mikepenz/release-changelog-builder-action@v4
              with:
                  token: '${{ github.token }}'

            - name: Create GitHub release
              uses: softprops/action-gh-release@v1
              with:
                  body: ${{steps.build_changelog.outputs.changelog}}

@softprops is this a feature that you intend to add? As there is a considerable amount of 👍 on the issue for this feature I'm curious if we should wait or to find a workaround.
