test(react-router): fix store-updates flakiness

[Sheraff]

This test has been yielding 7 or 8, let's just accept both, they're still reasonable anyway.

📝 Walkthrough

Walkthrough

This change relaxes strict test expectations in the store update count assertions, modifying two test cases to accept a range of 7–8 updates instead of exactly 7 updates during navigation with preloaded and async loaders.

Changes

Cohort / File(s)	Summary
Test Assertion Relaxation packages/react-router/tests/store-updates-during-navigation.test.tsx	Replaced strict equality checks (updates === 7) with range assertions (updates >= 7 && updates <= 8) in two test cases to accommodate variance in store update counts during navigation with async loaders

• refactor(router-core): loadMatches extra microtask #4967 — Modifies loader scheduling in loadMatches, which directly affects store update counts during navigation that this test measures.
• refactor(router-core): Verify changes are necessary before updating store #4964 — Updates the same test file with similar changes to expected update count assertions during navigation.
• refactor: don't reparse upon navigation #6398 — Refactors navigation timing and behavior, potentially explaining the variance in update counts that necessitated relaxing the test expectations.

Poem

🐰 A hop and a skip, the tests now align,
Seven or eight updates? Both are just fine!
No more brittle assertions to make developers weep,
Just flexible ranges for async loader's leap! ✨
