FOUND-2760 GitHub action for publishing

[hramniou-eurofunk]

Created a simple workflow using the Publishing-using-gradle GitHub action.

The workflow is executed once a GitHub Release is created. It uses ./gradlew publish command, which does publishing in the repository configured here:

sbom-license-plugin/build.gradle.kts

Lines 47 to 56 in 4fb1493

	repositories {
	maven {
	name = "GitHubPackages"
	url = uri("https://maven.pkg.github.com/eurofunk/sbom-license-plugin")
	credentials {
	username = project.findProperty("gpr.user") as String? ?: System.getenv("USERNAME")
	password = project.findProperty("gpr.key") as String? ?: System.getenv("TOKEN")
	}
	}
	}

The workflow sets${{ github.actor }} variable value for the USERNAME, and ${{ secrets.GITHUB_TOKEN }} for the TOKEN.
