Please don't remove the original xiontestnet. If it is no longer running, it should instead be marked as status "killed". Ideally, the currently running chain doesn't have any incrementing suffix, while archived chains do.
e.g.,
xiontestnet1 -> chain-id: xion-test-1
xiontestnet -> chain-id: xion-test-2

modified accordingly

There are assets registered that depend on IBC connections like these being registered. I think just changing the chain_name to "axelartestnet1" should suffice. (and in the file name)
