v3 to v4 messages should only be signaled once per session

[olivroy]

Thanks to #854, it is a little easier to know how to switch code from v3 to v4.

However, these messages can be a little overwhelming. As mentioned in https://github.com/r-tmap/tmap/issues/888#issuecomment-2162866397

I will wait for #851 to do this.

I will use cli to do this. https://rlang.r-lib.org/reference/abort.html#muffling-and-silencing-conditions
