sparse: parse and print patterns as workspace-relative paths

Per comment in
https://github.com/martinvonz/jj/pull/3379#pullrequestreview-1963841604

Though cwd-relative path might be useful for --remove, I don't think that's
the common use case. The new behavior is consistent with --edit.

 * The `git_head` template keyword now returns an optional value instead of a
   list of 0 or 1 element.
 
+* The `jj sparse` subcommands now parse and print patterns as workspace-relative

 ### New features
 
 * Config now supports rgb hex colors (in the form `#rrggbb`) wherever existing color names are supported.
