Add Rails 7.2 support

[andrewhampton]

After updating rails to 7.2.0 in my Gemfile, I receive this error:

❯ bundle
Fetching gem metadata from https://enterprise.contribsys.com/..
Fetching gem metadata from https://rubygems.org/........
Resolving dependencies...
Could not find compatible versions

Because paranoia >= 2.6.3 depends on activerecord >= 5.1, < 7.2
  and paranoia >= 2.5.0, < 2.6.3 depends on activerecord >= 5.1, < 7.1,
  paranoia >= 2.5.0 requires activerecord >= 5.1, < 7.2.
And because rails >= 7.2.0 depends on activerecord = 7.2.0,
  rails >= 7.2.0 is incompatible with paranoia >= 2.5.0.
So, because Gemfile depends on rails ~> 7.2.0
  and Gemfile depends on paranoia ~> 2.6,
  version solving has failed.
