As I am working on bringing the channel tagging UI to `web`, I noticed that the indexing in the tag channel button action sheet was broken. In D11894, I got some [[ https://phab.comm.dev/D11894?id=40260#inline-71371 | feedback ]] to make "Other" appear first, I addressed this feedback; however, I forgot to update the indexing to handle this change, so every option was off by one. This diff should fix this issue
