[Build] Update scalastyle config to not enforce a specific year for c…

…opyright

Updates the scalastyle config to accept years other than 2021 in the copyright header.

Note: This doesn't specify valid vs non valid years but accepts any 4 digit number. We can be more specific if desired.

Updates one file in Kernel to be "2023" which fails without this change.

Closes delta-io#1970
