fix(ktor): bump to 3.0.0

[monosoul]

Using current version of cohort with Ktor 3.0.0 causes the following exception:

Exception in thread "main" java.lang.NoClassDefFoundError: io/ktor/server/routing/RoutingKt
	at com.sksamuel.cohort.PluginKt$Cohort$2.invoke(plugin.kt:14)
	at com.sksamuel.cohort.PluginKt$Cohort$2.invoke(plugin.kt:11)
	at io.ktor.server.application.CreatePluginUtilsKt.setupPlugin(CreatePluginUtils.kt:276)
	at io.ktor.server.application.CreatePluginUtilsKt.createPluginInstance(CreatePluginUtils.kt:245)

	at io.ktor.server.application.ApplicationPluginImpl.install(CreatePluginUtils.kt:71)
	at io.ktor.server.application.ApplicationPluginKt.install(ApplicationPlugin.kt:100)

since routing method is now located in RoutingRoot.kt instead of Routing.kt. Compiling cohort against Ktor 3.0.0 will fix that.

I've also added foojay plugin to resolve Java toolchains automatically with Gradle.

As a workaround one can copy plugin.kt and endpoints.kt into their own project for now.

When copying plugin.kt make sure to NOT copy CohortConfigAttributeKey definition, instead import com.sksamuel.cohort.CohortConfigAttributeKey.

@monosoul I tried to apply the workaround, but it didn't work for me. Maybe i'm missing something. Could you explain the workaround more detailed?
