### Rationale for this change UUID extension types were made canonical in #41299 and are getting native support in C++ and Python in #37298. As such, it makes sense to provide an alternative user-defined extension type as an example that is unlikely to become a canonical extension type anytime soon. After discussion in #43809, we determined a `RationalType` would make sense. ### What changes are included in this PR? A change in several doc locations which reference a `UuidType` extension type have been changed to a `RationalType`. ### Are these changes tested? I've run all the code in the docs locally. I'm not sure if Arrow runs doctests, but welcome information on how to enable those for these changes. ### Are there any user-facing changes? No. cc @ianmcook @rok -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
