[PATCH b4 2/3] review: sashiko: fix URLs

The displayed URL is currently leading to a 404, e.g.

  https://sashiko.dev/patch/93

I don't know if this URL was working at some points, but it is no longer
now. This one works:

  https://sashiko.dev/#/patchset/93

And in case of a series, ?part=X can be used, e.g.

  https://sashiko.dev/#/patchset/93?part=2
