chore: Bump Pytest from 8.4.2 to 9.0.0+

[vdusek]

Summary

• Bumps pytest from 8.4.2 to 9.0.3
• Relaxes the upper bound constraint from <9.0.0 to <10.0.0
• Includes fix for CVE-2025-71176 (use of insecure temporary directory)

Same update as apify/apify-client-python#721

Why wasn't this done by Renovate?

Renovate opened a PR for pytest v9 back on 2025-11-10, but the uv lock resolution failed because pytest-asyncio~=1.2.0 at the time required pytest>=8.2,<9 — making it incompatible with pytest 9. The PR was closed, and Renovate's ignore logic kicked in:

Because you closed this PR without merging, Renovate will ignore this update. You will not get PRs for any future 9.x releases.

Since then, pytest-asyncio has released a version compatible with pytest 9, resolving the conflict. But Renovate never retried because its "close = ignore forever" behavior blocked all future 9.x PRs. A manual upgrade (this PR) is needed to unblock Renovate for future pytest updates.
