Update README with missing feature descriptions

Add undocumented features found by inspecting src/:
- Array access component type resolution via createComponent*
- Forms\Container::getUntrustedValues return type
- BaseControl fluent method static return type
- Presenter::getSession return type based on arguments
- Presenter @Inject properties treated as initialized
- Strings::replace() callback closure type from regex pattern
- RegularExpressionPatternRule for Nette\Utils\Strings methods

 This extension provides following features:
 
 * `Nette\ComponentModel\Container::getComponent()` knows type of the component because it reads the return type on `createComponent*` (this works best in presenters and controls)
+* Array access on components (`$component['name']`) resolves types via `createComponent*` methods
 * `Nette\DI\Container::getByType` and `createInstance` return type based on first parameter (`Foo::class`).
 * `Nette\Forms\Container::getValues` return type based on `$asArray` parameter.
+* `Nette\Forms\Container::getUntrustedValues` return type based on mapping class parameter.
+* `Nette\Forms\Controls\BaseControl` fluent methods return `static` instead of `BaseControl`.
 * `Nette\ComponentModel\Component::lookup` return type based on `$throw` parameter.
 * `Nette\Application\UI\Component::getPresenter` return type based on `$throw` parameter.
+* `Nette\Application\UI\Presenter::getSession` returns `Session` or `SessionSection` based on arguments.
 * Dynamic methods of [Nette\Utils\Html](https://doc.nette.org/en/2.4/html-elements)
 * Magic [Nette\Object and Nette\SmartObject](https://doc.nette.org/en/2.4/php-language-enhancements) properties
 * Event listeners through the `on*` properties
+* Presenter `@inject` properties are treated as initialized.
 * Defines early terminating method calls for Presenter methods to prevent `Undefined variable` errors
 * Understand the exact array shape coming from `Nette\Utils\Strings::match()` and `Nette\Utils\Strings::matchAll()` based on pattern
+* `Nette\Utils\Strings::replace()` callback closure parameter type inferred from regex pattern
 
 It also contains these framework-specific rules (can be enabled separately):
 
 * Do not extend Nette\Object, use Nette\SmartObject trait instead
 * Rethrow exceptions that are always meant to be rethrown (like `AbortException`)
+* Validate regex patterns passed to `Nette\Utils\Strings` methods
