Add new config `--release-prefix` for addRelease and createGithubRelease

[WengerK]

💬 Describe the pull request

For now, the chan-cli and chan-core packages use an hardcoded release/tag prefix v. Used for tagging release & gh-release. Some company or person may need to handle the version tagging with another or no prefix.

This PR intend to allow anybody to choose another prefix by using a new configuration named --release-prefix.
