feat: mark exportMode and fileIds as deprecated in add_distribution()

[Copilot]

The Crowdin API has deprecated exportMode and fileIds parameters on the Add Distribution endpoint. This updates the Python client to surface those deprecations via DeprecationWarning while preserving full backward compatibility.

Changes

• resource.py: Emit DeprecationWarning when exportMode or fileIds are passed to add_distribution(); change exportMode default from ExportMode.DEFAULT → None so it is omitted from the request body when not explicitly set
• tests/: Wrap existing test cases using deprecated params with pytest.warns(DeprecationWarning); update expected request_data to reflect new exportMode default; add a test covering the no-deprecated-params path

Example

# These now emit DeprecationWarning but continue to work
resource.add_distribution(name="dist", projectId=1, fileIds=[1, 2, 3])
resource.add_distribution(name="dist", projectId=1, exportMode=ExportMode.BUNDLE)

# Recommended going forward
resource.add_distribution(name="dist", projectId=1, bundleIds=[42])

This section details on the original issue you should resolve

<issue_title>Mark deprecated Distribution create params</issue_title>
<issue_description>The Crowdin API marks exportMode and fileIds request parameters in the Add Distribution method as deprecated.

The Crowdin API client libraries should be updated to mark these parameters as deprecated in SDK method signatures, so developers are clearly guided away from using them while keeping backward compatibility.
