doc/conf: use stable year for man page generation

Updating the man pages should always be an explicit action. We rely on
stable output and keep the generated man pages tracked in git for
easy packaging. The CI jobs generate the man pages and check for diffs.

Using the current year obviously breaks this process, so set the year to
an explicit value that can be updated when required.
