Switch to GitHub Actions (#48)

This Switches from Travis-CI to GitHub Actions due to the recent
changes to Travis-CI that remove OSS runs.

New deploy key and secret key have already been added to the
repository.

TagBot is also updated to the latest version, see https://github.com/JuliaRegistries/TagBot

 A PowerModelsRestoration provides extensions to [PowerModels](https://github.com/lanl-ansi/PowerModels.jl) for solving the power system restoration tasks.  A core building block in PowerModelsRestoration is the Maximum Load Delivery (MLD) problem, which provides a reliable numerical method for solving challenging N-k damage scenarios, such as those that arise in the analysis of extreme events.
