### Explanation of Changes

1. **Added `python311-sphinx_rtd_theme`, `python312-sphinx_rtd_theme`, and `python313-sphinx_rtd_theme` as `BuildRequires`**:
   - These packages ensure that the `sphinx_rtd_theme` module is available for all supported Python versions during the build process.

2. **Fixed the `%python313_provides` Macro Issue**:
   - Removed any unexpected arguments from the `%python313_provides` macro invocation. If the macro is still causing issues, it may need further clarification or adjustment based on the specific RPM macros defined in the build environment.

3. **Ensured Consistency Across Python Versions**:
   - The build process iterates over all supported Python versions (`python311`, `python312`, `python313`) to ensure compatibility.

### Next Steps

After applying these changes, rebuild the package using the same build environment. If additional errors arise, they will need to be diagnosed and addressed accordingly.
