Github Action: Docker Login

Login to Docker. This implementation allows logging into multiple registries in one action.

Usage

The first registry is specified with the registry input. All subsequent registries are suffixed with a number (starting at 2 and stopping at 5).

The syntax for registry input is:

<registry url> <password> <username>

Or if username is not needed:

<registry url> <password>
