These changes ensure that the latest package versions are reflected in the pyproject.toml files, aligning with the project's release process.

Why

The version bumps are necessary to:

• Reflect the latest changes and improvements in each package.
• Ensure consistency across related projects (gaussdb and gaussdb_pool) by aligning their versions.
• Prepare for a new release of the isort_gaussdb plugin with updated functionality or fixes.
• Maintain accurate versioning in the pyproject.toml files as per the project's release process.

Testing

• Verified that the version numbers in the respective pyproject.toml files were updated correctly.
• Ensured that the comments in the pyproject.toml files (e.g., instructions for updating docs/news.rst or gaussdb_c/pyproject.toml) remain intact and accurate.
• Confirmed that no additional changes were introduced beyond the version updates.
• Ran a local build test (python -m build -o dist --wheel) for isort_gaussdb to ensure the new version is buildable.
