Find a way to use same Spine versions source for buildSrc/build.gradle.kts and deps.kt #3
Description
While we're using Kotlin DSL pre-compiled plugins, we currently have bootstrap version declared in one place and gcloud version declared in the other.
We're actually facing a chicken and an egg issue here, cause we're compiling deps.kt using buildsrc/build.gradle.kts and thus are not able to use versions from deps.kt in the build script.
Also, in order to be able to configure plugins inside pre-compiled script plugins such as java-convention.gradle.kts, we must declare all the dependent plugins inside the build.gradle.kts.
Maybe there could be some way to extract Spine versions into a separate .properties file and read its content from both build.gradle.kts and deps.kt in order to have the same source of versions for both. An easy approach to extract smth like version.gradle.kts as we have in the main repo does not work, we're not able to propagate things from extra to deps.kt.
