Merge bitcoin/bitcoin#29498: test: Update --tmpdir doc string to say directory must not exist

d4e36ae80d test: Update --tmpdir doc string to say directory must not exist (kevkevin)

Pull request description:

  The error message given if passing an existing dir to --tmpdir is confusing so this makes it clear that the directory must not already exist

  This change is motivated by this comment https://github.com/bitcoin/bitcoin/pull/29335#issuecomment-1960913020
