Pull request: build: add create release proposal action

Blocked until the following PR lands

* https://github.com/nodejs/node-core-utils/pull/862
* https://github.com/nodejs/node-core-utils/pull/863
* https://github.com/nodejs/node-core-utils/pull/864

Refs: https://github.com/nodejs/security-wg/issues/860

The purpose is to have an action that will generate the release proposal (assuming the vN.x-staging is up to date). After that, I'll create a second action the keep the staging branches up-to-date.
