zeekayandHanzo Dev aa87442fdd Record upstream authorship centrally in NOTICE instead of in every file header
Source files keep their SPDX-License-Identifier and Hanzo copyright line; the
Gitea, Gogs and LFS Test Server copyrights they used to repeat now live once in
NOTICE, alongside LICENSE. The header lint accepts any copyright line above the
SPDX line, so it no longer demands an upstream one.
