docs: clarify that failureCount starts at 0 in retry callback

[lourq]

Summary

Added clarification that failureCount parameter in the retry callback function starts at 0 for the first retry attempt, not 1.

Changes

• docs/framework/react/guides/query-retries.md: Added note about failureCount starting at 0
• docs/framework/react/reference/useQuery.md: Added explanation for the function variant of retry option

This helps developers understand that on the first retry check, failureCount will be 0, which can be surprising if not documented.

Fixes #10017

Summary by CodeRabbit

• Documentation
  • Clarified retry functionality documentation to explain that the failureCount parameter starts at 0 for the first retry attempt and is provided to custom retry functions alongside the error for retry decision-making.

Poem

🐰 A curious hop through the retry chain,
Where failureCount starts fresh, clear as rain,
Zero, not one, the docs now declare,
So no more confusion in the retry snare!

13-13: LGTM! Clear documentation of failureCount behavior.

The added clarification that failureCount starts at 0 for the first retry attempt directly addresses the confusion reported in issue #10017 and will help developers understand the expected behavior when implementing custom retry logic.

87-87: LGTM! Consistent and helpful clarification.

The documentation accurately clarifies that failureCount starts at 0 for the first retry, which is consistent with the change in the guides file and addresses the documentation gap identified in issue #10017.
