Coursier throws a FileNotFoundException

[lefou]

While running mill mill.scalalib.Dependency.updates Mill aborted abnormally with the following exception, which is most likely a concurrency issue in coursier, seen before but deemed to be fixed.

A subsequent run succeeded, so this is indeed on of the issues we previously handled in Mill with retry-logic and removed it later in #3505.
