Updating the Retype app

Here are a few notes on updating the retype app. I originally installed it with the dotnet command, so I have to continue using dotnet to update the retypeapp.

dotnet tool update retypeapp -g --version 4.5.0-preview5

However for the retype-action.yml in GitHub, this will get it to build:

 - uses: retypeapp/action-build@next
