PATCH: complete for tmux server-access

[Oliver Kiddle <opk@xxxxxxx>]

I just applied github PR #106 for tmux completion. That removed the
server-info subcommand and added server-access. However the remaining
comment, description and (lack of) completion didn't look right for
server-access. So this patch handles server-access properly and a few
other new options, Although I'm using tmux 3.3a rather than the latest
snapshot which is what the github contributor appears to be using.
