build(deps): update sphinx-autodoc-typehints requirement from >=1.8.0 to >=3.15.0 - #264

Sourced from sphinx-autodoc-typehints's releases.

3.15.0

• Allow projects to show selected Annotated metadata in rendered types with typehints_annotated_metadata. #1071
• Process method signatures of classes defined inside functions when the module exports the class under a name autodoc can import. #1072
• Let typehints_formatter receive whether a type appears in a parameter, return, attribute or base when typehints_formatter_pass_context is enabled. #1073
• Reread documents when typehints_formatter changes in an incremental build, so their rendered types update without sphinx-build -E. #1069
• Stop an unchanged incremental build from reporting html_static_path as changed after the extension adds its stylesheet. #1070
• Document inherited special methods of a generic subclass without raising Cannot subscript already-subscripted typing.Generic. #1074
• Show a property setter's type when Annotated metadata raises during comparison with the getter type, instead of failing the build. #1076
• Keep the description in a hand-written :Returns: field instead of interpreting it as a numpydoc return type. #1077
• Skip imports under if TYPE_CHECKING and False instead of resolving types the branch never defines. #1078
• Advertise Sphinx, autodoc and type hints in the PyPI keywords instead of unrelated virtual environment terms, and add classifiers for documentation, OS independence and the package's type annotations. #1068

3.16.0 (2026-10-17)
