devel/got: update to 0.98

User-visible changes:

• speed up got tag -l by caching timestamps
• make 'got ref -l' output consistent when packed references exist
• make 'got ref -l' work consistently when a reference argument is given
• add log -t option which enables topological sorting of commits
• make 'got rebase' find a merge base with topological sorting if needed
• make 'got status' display interrupted rebase, histedit, and merge operations
• add http clone/fetch support using a new got-fetch-http helper
• require -R option for staging or unstaging directory contents
• got patch: fix applying on empty files

HTTP(S) clone/fetch requires the "smart" Git protocol. It works with
GitHub, Codeberg, Savannah. Also git.freebsd.org, but you should use
anon-ssh there.
