Mention Rails 7.1 isolation_level config

[santib]

The other day I was trying Falcon for the first time on a I/O bound Rails app. While I was testing I started seeing very strange errors when doing simple DB queries (PostgreSQL), for example primary_key not found for table x. Fortunately, after some research, I realized I needed switch a new Rails 7.1 config. When I did that I was amazed to see how everything started to work just fine, and feeling grateful we have an evented web server ready to be used along with Rails (thanks 🙌).

I added the config change to the top of the docs so we make sure nobody makes the same mistake, but I'm wondering if this should be turned on automatically by falcon using a Railtie?

I think this sounds super. Thank you for sharing your experience.

I've also proposed adding support for this using rails new --server falcon.
