We accidentally marked every "any" and "unknown" types as optional, regardless if the declaration had a question mark or not. Fixes #284
Since most languages do not have a distinction between "null" and "undefined", jsii will effectively convert any "null" value passed into an argument, a property or inside an object to "undefined". Adds a compliance test to Java and .NET called "NullShouldBeTreatedAsUndefined". Fixes aws/aws-cdk#157 Fixes #282

…3 in /packages/@jsii/python-runtime (#3785) Updates the requirements on [cattrs](https://github.com/python-attrs/cattrs) to permit the latest version. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/python-attrs/cattrs/blob/main/HISTORY.rst">cattrs's changelog</a>.</em></p> <blockquote> <h2>22.2.0 (2022-10-03)</h2> <ul> <li><em>Potentially breaking</em>: <code>cattrs.Converter</code> has been renamed to <code>cattrs.BaseConverter</code>, and <code>cattrs.GenConverter</code> to <code>cattrs.Converter</code>. The <code>GenConverter</code> name is still available for backwards compatibility, but is deprecated. If you were depending on functionality specific to the old <code>Converter</code>, change your import to <code>from cattrs import BaseConverter</code>.</li> <li><code>NewTypes <https://docs.python.org/3/library/typing.html#newtype></code>_ are now supported by the <code>cattrs.Converter</code>.

(<code>[#247](python-attrs/cattrs#247) <https://github.com/python-attrs/cattrs/pull/247></code>_)</li> <li>PyPy support (and tests, using a minimal Hypothesis profile) restored.

Switch to <code>typing.AbstractSet</code> on those versions to restore the old behavior. (<code>[#264](python-attrs/cattrs#264) <https://github.com/python-attrs/cattrs/issues/264></code>_)</li> <li>Uncap the required Python version, to avoid problems detailed in <a href="https://iscinumpy.dev/post/bound-version-constraints/#pinning-the-python-version-is-special">https://iscinumpy.dev/post/bound-version-constraints/#pinning-the-python-version-is-special</a> (<code>[#275](python-attrs/cattrs#275) <https://github.com/python-attrs/cattrs/issues/275></code>_)</li> <li>Fix <code>Converter.register_structure_hook_factory</code> and <code>cattrs.gen.make_dict_unstructure_fn</code> type annotations.

(<code>[#218](python-attrs/cattrs#218) <https://github.com/python-attrs/cattrs/issues/218></code>_)</li> <li>Fix a wrong <code>AttributeError</code> of an missing <code>__parameters__</code> attribute. This could happen when inheriting certain generic classes – for example <code>typing.*</code> classes are affected. (<code>[#217](python-attrs/cattrs#217) <https://github.com/python-attrs/cattrs/issues/217></code>_)</li> <li>Fix structuring of <code>enum.Enum</code> instances in <code>typing.Literal</code> types.
