Release 1.0.3 doesn't find module '@actions/core'

[jheilgeist]

Our builds broke shortly after the new release 1.0.3 arrived. I've tested the build with @stable, @1.0.0, and @1.0.3: @stable/@1.0.3 fail, while @1.0.0 works as expected.

How we use the action:

- name: Delete Previous Release
  uses: author/action-rollback@stable
  # step fails, if tag doesn't exist in the first place; but that's ok!
  continue-on-error: true
  with:
    tag: ${{ env.release_tag }}
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

How it fails with 1.0.3:

Run author/action-rollback@1.0.3
internal/modules/cjs/loader.js:800
    throw err;
    ^

All my github actions broke because of this release :( Looks like its because the node_modules folder was removed. I know there's a way to get it to work without that folder but right now it seems like its not.

Also I created a tag-exists action just for this purpose @jheilgeist : https://github.com/marketplace/actions/tag-exists-action

I've just reverted the change. My apologies to those affected. It does look like it's just the missing dependency, but I'll update later (not this week) after I can test more thoroughly.
