Update README with missing Dibi\Row feature description

The README only described the Dibi\Fluent dynamic method support but
omitted the Dibi\Row universal object crate feature that is registered
in extension.neon. Added a complete feature list covering both
capabilities of the extension.

+This extension provides the following features:
+
+* Defines dynamic methods on `Dibi\Fluent` instances. They are called to build an SQL query dynamically. Each dynamic method accepts variadic arguments and returns `Dibi\Fluent` for method chaining.
+* Registers `Dibi\Row` as a universal object crate, allowing dynamic property access without errors.
