Add support .md file in body

[solairen]

Hi,
I'm wondering if there is any chance to add support to include .md file in body section. Right now, to show all issues from project, you have to add them manually to body.

How it works now

with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          body: |
            Some text
            [issueNumber](issueLink)
          draft: false
          prerelease: false

Additional option

with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          body.file: |
            body.md
          draft: false
          prerelease: false

The result of additional option will be shown in Release section, all issues created in project from body.md file

👋 I actually submitted a PR for this in #50. We will wait and see how it goes over.

Seems like this is a function that many people wants to have, hope it will be added to this action.

Finger crossed ;)

I have a version available on my fork that you may use in the meantime. I intend to leave it up for the foreseeable future.

I have created a Repository Attributes Action to make some common metadata such as contributors, changed files, PRs, and commits available to be included in the release body.
