feat: add Style Guides API support

[innomaxx]

Closes #247

[Copilot]

Pull request overview

Adds Style Guides API support to the Crowdin Python client by introducing a new StyleGuidesResource (list/create/get/delete/patch) exposed via CrowdinClient.style_guides, along with corresponding enums, TypedDict request shapes, and unit tests. Resolves issue #247.

Changes:

• New style_guides package (resource, enums, types, __init__) with CRUD methods under the style-guides path.
• Re-exports StyleGuidesResource from crowdin_api/api_resources/__init__.py and wires it as a CrowdinClient property.
• Adds resource unit tests following the existing pattern; also alphabetizes a few existing imports.
