v2.0

• Added a gate mode config that allows you to choose to only open Gate A or B, open both, or choose randomly each time (set to both by default)
• Increased the default closing time from 20 seconds to 30 seconds
• Changed some of the wording in the config and readme to clarify that the countdown starts when the nuke button is pressed
• The project now uses .NET SDK 8+, allowing it to be built on Linux
• The EXILED assemblies are now included as a Nuget package, so now only the dedicated server assemblies need to be manually configured when forking the project
