Fix PR, Update dependencies.

[luca992]

There was a bunch of build issues with your PR. If fixed the build and further updated ktor and plugins

Edit:

If you build as is:

1. gradlePluginPortal() isn't added to buildscript.repositories and it fails there
2. Build fails if extra publishing properties aren't present (which isn't necessarily a bug, but it's easy enough to fix by doing as String -> as String? ?: "")
3. The error: Minimum supported Gradle version is 7.2. Current version is 7.1.1. (I updated to 7.4.2)
4. bodyAsChannel() uses the wrong import in HttpFetcher
