NetDaemon 5, .NET 9 release

[helto4real]

Proposed change

Yay! It is that time of the year when the .NET community can benefit from more innovations and more performant .NET based solutions. This PR upgrades the NetDaemon to version 5 and support .NET 9. As usual for a new .NET version we also increment the NetDaemon main version. After this PR is merged, all new features and fixes will be in this version.
TODO in this PR:

• Update builds and github actions
• Update the docker base images
• Update to use C# 13
• Upgrade to .NET dependencies
• Manual testing by releasing an alpha release

Other todo in other repos

• Add new addon for version 5 and .net 9
• Update the cli tool to use .net 9
• Update docs where it references .net 8 and change to .net 9

Breaking change

Except for new dependecy on .NET 9 SDK, code should be compatible. Please install .NET 9 SDK before using this version or use the .NET 9 docker/add-on versions.
