Update build and publish commands in Docker action

The Docker workflow in the GitHub Actions pipeline has been modified to specify the project file in the build and publish commands. Previously, the build and publish commands did not specify the project file, which could potentially cause issues if multiple project files exist in the solution. Now, these commands explicitly target the 'DiscordMonies/DiscordMonies.csproj' file for building and publishing.
