Unable to find credentials for [GitHub Package Registry @ maven.pkg.github.com]

Hi, first of all thanks for making this amazing project!

I am trying to use it to publish on github packages using github actions. But facing the following error.

Error:

Things that I have tried

• Checked if the token has permissions, and it does.

Update 1
Updating the publishSettings method to the following worked

def publishSettings(projectName: String) = Seq(
  publish / skip := false,
  name           := projectName,
  versionScheme  := Some("early-semver"),
  publishTo      := Some("GitHub Package Registry" at s"https://maven.pkg.github.com/tusharmath/zio-compose"),
  credentials += Credentials("GitHub Package Registry", "maven.pkg.github.com", "tusharmath", sys.env("GITHUB_TOKEN")),
  organization   := "io.github.tusharmath",
)

Start with the build.sbt publishSettings method and compare the failing configuration with the working update in the issue. Check how credentials are resolved for the GitHub Package Registry during the GitHub Actions publish run. Done means the configured publish task finds the credentials and uploads the package without the 401 error.
