Eliminate the Akka CLA?

[dwickern]

Contributors to sbt-native-packager are required to sign the Akka CLA. As far as I know, sbt-native-packager has no relationship with Akka (the product) or Akka (the company, formerly Lightbend/Typesafe). Can we get rid of it?

Other projects in the ecosystem changed their CLA after Akka's license change in 2022:

• Play Framework removed the CLA - https://github.com/orgs/playframework/discussions/11405 Removing CLA from the PR template. playframework/playframework#11407
• Slick removed the CLA - .mergify.yml: don't require signing Lightbend CLA slick/slick#2590
• SBT transferred to the Scala Center and switched to the Scala CLA - Clarity of CLA sbt#7048 Transfer copyright to the Scala Center sbt#7306
