Sylabs originated content vs LICENSE copyright years

[dtrudg]

Hi all,

You have been bringing in some 2021 changes from the Sylabs documentation repositories, e.g. #140

Your LICENSE file is only listing copyright for Sylabs up to 2020, not 2021.

Please could you ensure on admindocs and userdocs that the copyright attribution matches the years for which you have brought content over from the Sylabs repositories.

Thanks!
