Hi,

I've tried this action today and am very happy to have created this workflow with it :)
One thing that made the creation a bit complicated for me was that the new-version contained a trailing newline as can be seen in this action run:

The output of

    - name: Log some stuff
      run: |
        echo "Line One"
        echo "${{ steps.dependabot-metadata.outputs.previous-version }}"
        echo "Line Two"
        echo "${{ steps.dependabot-metadata.outputs.new-version }}"
        echo "Line Three"
        echo "Line One"
        echo "${{ steps.version-numbers.outputs.previous-version }}"
        echo "Line Two"
        echo "${{ steps.version-numbers.outputs.new-version }}"
        echo "Line Three"

(the version-numbers step is my manual approach of stripping the whitespaces) is

  echo "Line One"
  echo "0.23.3"
  echo "Line Two"
  echo "0.24.1
  "
  echo "Line Three"
  echo "Line One"
  echo "0.23.3"
  echo "Line Two"
  echo "0.24.1"
  echo "Line Three"

I'm not sure if this problem is specific to the pip ecosystem and/or may also happen for previous-version, but it would be nice if fetch-metadata could strip leading and trailing whitespaces automatically :)

Cheers,
Hinrich
