tag doc: move the description of --[no-]merged earlier
Move the documentation for the --merged & --no-merged options earlier in the documentation, to sit along the other switches, and right next to the similar --contains and --points-at switches. It makes more sense to group the options together, not have some options after the like of <tagname>, <object>, <format> etc. This was originally put there when the --merged & --no-merged options were introduced in 5242860f54 ("tag.c: implement '--merged' and '--no-merged' options", 2015-09-10). It's not apparent from that commit that the documentation is being placed apart from other options, rather than along with them, so this was likely missed in the initial review.
