Add Support for External Release Repository (#114)

* Add Support for External Release Repository

This adds a feature where we can publish the release to an external
repository, a good use case on this is when you have a private
repository and wish to publish binaries to the public.

* Add release_repo to README.md

 | sha256sum | **Optional** | Publish `.sha256` along with artifacts, `FALSE` by default. |
 | release_tag | **Optional** | Target release tag to publish your binaries to. It's dedicated to publish binaries on every `push` into one specified release page since there's no target in this case. DON'T set it if you trigger the action by `release: [created]` event as most people do.|
 | release_name           | **Optional**               | Alternative to `release_tag` for release target specification and binary push. The newest release by given `release_name` will be picked from all releases. Useful for e.g. untagged(draft) ones.|
+| release_repo           | **Optional**               | Repository where the build should be pushed to. By default the value for this is the repo from where the action is running. Useful if you use a different repository for your releases (private repo for code, public repo for releases).|
 | overwrite | **Optional** | Overwrite asset if it's already exist. `FALSE` by default. |
 | asset_name | **Optional** | Customize asset name if do not want to use the default format `${BINARY_NAME}-${RELEASE_TAG}-${GOOS}-${GOARCH}`. <br>Make sure set it correctly, especially for matrix usage that you have to append `-${{ matrix.goos }}-${{ matrix.goarch }}`. A valid example could be  `asset_name: binary-name-${{ matrix.goos }}-${{ matrix.goarch }}`. |
 | retry | **Optional** | How many times retrying if upload fails. `3` by default. |
