exporting changelog entry to tmp file

[jon-whit]

Would you be open to a contribution that allows changelog-reader-action to export a tmp file path that contains the changelog entry? This would be helpful to avoid shell escape sequence on richer markdown content. I've ran into issues with this for integrations that require a path to a file containing release notes (like goreleaser for example). I'd be happy to contribute this feature if you'd be open to it 👍

I was thinking:
outputs.changesFile - a path to a temporary file containing the text for the changelog entry.

Then I can use it like so:

name: release

on:
  push:
    tags:
      - 'v*'

jobs:
  goreleaser:
    runs-on: ubuntu-latest
    steps:
      - name: Extract Version from Tag
        id: tag_name
        run: |
          echo ::set-output name=current_version::${GITHUB_REF#refs/tags/v}
        shell: bash

      - name: Checkout
        uses: actions/checkout@v2
        with:
          fetch-depth: 0

      - name: Generate Release Changes
        id: changelog_reader
        uses: mindsers/changelog-reader-action@v2
        with:
          version: ${{ steps.tag_name.outputs.current_version }}

      - name: Set up Go
        uses: actions/setup-go@v2
        with:
          go-version: 1.18

      - name: Login to Docker Hub
        uses: docker/login-action@v2
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_TOKEN }}

      - name: Run GoReleaser
        uses: goreleaser/goreleaser-action@v2
        with:
          distribution: goreleaser
          version: latest
          args: release --rm-dist --release-notes ${{ steps.changelog_reader.outputs.changesFile }}
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Hi! Thanks for submitting this issue! ❤️

This is definitely an interesting idea. I think it'll make changelog-reader even more useful.
And I really appreciate that you offer to contribute.

I'm wondering if other data (other than the entry's content) could be useful as a temporary file also?
