Support file_fixture in Factory definitions

Related to [factory_bot#1282][]

[rails/rails#45606][] has been merged and is likely to be released as
part of Rails 7.1.

With that addition, the path toward resolving [factory_bot#1282][]
becomes more clear. If factories can pass along [Pathname][] instances
to attachment attributes, Active Support will handle the rest.

Instances of `ActiveSupport::TestCase` provide a [file_fixture][] helper
to construct a `Pathname` instance based on the path defined by
`ActiveSupport::TestCase.file_fixture_path` (relative to the Rails root
directory).
