docs: remove fga_client.close() from README (#191)

[JsMelix]

Description

Removes the unnecessary fga_client.close() call from the README example.

What problem is being solved?

The example included a .close() call, but the Python SDK automatically handles client closing via context managers, so users don't need to call it manually.

How is it being solved?

By removing the redundant line from the README documentation.

What changes are made to solve it?

• Updated README.md
• Improved example clarity

References

Closes #191

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check	✅ Passed	The PR title "docs: remove fga_client.close() from README (#191)" is concise, specific, and directly related to the main change described in the raw_summary. The title clearly communicates that the PR removes explicit close calls from the README examples, which is exactly what the changeset accomplishes. The title uses appropriate prefixing ("docs:") to indicate it's a documentation change and includes the issue number for reference, making it clear and actionable for developers scanning the history.
Linked Issues Check	✅ Passed	The PR directly addresses the objective from issue #191 by removing explicit fga_client.close() calls from the README examples within async-with blocks. The raw_summary confirms that the changes align with the issue's requirement to eliminate redundant manual close calls since context managers (with __aexit__() and __exit__() methods) already handle resource cleanup automatically. The PR fully satisfies the coding requirement specified in the linked issue without introducing unrelated changes.
Out of Scope Changes Check	✅ Passed	The PR introduces only in-scope changes focused entirely on addressing issue #191. The raw_summary indicates that only README.md was modified, with changes limited to removing explicit close calls from async-with block examples. No unrelated modifications, refactoring, or feature additions are present. The changes are directly tied to the documented objective of improving README example clarity by removing unnecessary manual close calls.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.
