Work related to rogchap#165

- Created an scheduled workflow that runs every month, which
automated the steps to upgrade the v8 binaries from source
https://github.com/rogchap/v8go#upgrading-the-v8-binaries

- Created a new workflow that is triggered by a pull_request
which build the v8 binaries for MacOs and Linux. Window
is excluded until we figured out a way to solve the compiler
issues.
