build(gradle): Kotlin DSL build and Dependabot

[stachu540]

Prerequisites for Code Changes

• This pull request follows the code style of the project
• I have tested this feature

Changes Proposed

1. Revmap build to kotlin-dsl
2. creating .github/dependabot.yml for dependencies

Additional Information

Revmaped build to Kotlin DSL will help simplify build library. Creating buildSrc and provide function and his extensions gives oportunity to doing some cleanup. Of course created gradle.properties provides only group and version. If you wish extracting version from environmental variables i can move it to buildSrc/src/main/kotlin/_globals.kt which are having more environmental variables definition into property when they are accessible for all projects. All changes are tested without no issue (for now). WARNING: Do not add apply false into plugins definition. It cause exceptions of missing properties or functions, which are be not loaded if you didn't apply plugin inside the file. More about cross configuration project will find here

Dependabot is supported for Kotlin DSL. Preview version doesn't have it this feature.

After resolving #244 i will start resolve this PR. For now marking him as Draft.

I'll hold kotlin dsl changes. The bug is more complex that we can imagine it. Extended functions defined for dependencies will be break it, if you try fetching jar resources classes (I think). To avoid that we will use a quoted configuration like that: "implementation"(project(":common")). This feature provided from shadow plugin breaks a configurations defined in kotlin-dsl's extended functions.

Simple: Using kotlin-dsl with shadow pluigin and define this lines ,and will disallow loading extended functions, resolving errors of unknown extended function. This should be fixed only quoting configuration name as mentioned above.

artifactId will be setted in here

Yes, but the generated artifactId's from the module names don't match the existing artifact names we published in the past, so i used fixed values everywhere to make sure it's pushed correctly.
For example the artifactId for helix should be twitch4j-helix, while the module name rest-helix would end up as twitch4j-rest-helix - thats why i set the artifactId in each module.
