Appending release note now fail

[RadxaYuntian]

2 weeks ago the action was working: https://github.com/radxa-pkg/radxa-overlays/actions/runs/14512172143/job/40713439773
Now with the same input it will fail: https://github.com/radxa-pkg/edk2-cix/actions/runs/14699628860/job/41246948535

Both uses the following snippet:

    - name: "Append changelog"
      uses: "softprops/action-gh-release@v2"
      with:
        append_body: true
        body: |
          ## Changelog for ${{ env.version }}
          ${{ env.changes }}
        tag_name: "${{ env.version }}"

Umm an older version of workflow worked: https://github.com/radxa-pkg/cix-profiles/actions/runs/14701340085/workflow#L70-L92

After #665 is merged I'm still getting broken workflow when trying to update release note:

Cannot reproduce this issue with the latest v2.5.2 release. If you're still seeing a different failure on current releases, please open a new issue with a fresh repro or sanitized workflow snippet so we can investigate it separately.
