Angular docs: useIsFetching not converted to injectIsFetching in background-fetching-indicators guide

[wook95]

Describe the bug

The Angular version of the background-fetching-indicators guide shows React's useIsFetching hook instead of Angular's injectIsFetching function. This happens because the Angular guide references the React guide but lacks the replace rules that other Angular guides have.

The file docs/framework/angular/guides/background-fetching-indicators.md references React documentation but doesn't convert React-specific APIs to Angular equivalents, causing confusion for Angular users.

Your minimal, reproducible example

N/A - This is a documentation issue. You can see the problem by visiting: https://tanstack.com/query/latest/docs/framework/angular/guides/background-fetching-indicators The second code example shows useIsFetching which doesn't exist in Angular Query.

Steps to reproduce

1. Go to Angular Query documentation
2. Navigate to 'Background Fetching Indicators' guide
3. Scroll down to 'Displaying Global Background Fetching Loading State' section
4. See useIsFetching instead of injectIsFetching

Expected behavior

As an Angular user, I expected to see injectIsFetching from @tanstack/angular-query-experimental but I am seeing useIsFetching from @tanstack/react-query.

How often does this bug happen?

Additional context

All other Angular guides properly convert React hooks to Angular inject functions using replace rules in their frontmatter. This guide is missing:

replace: { 'useIsFetching': 'injectIsFetching', 'hook': 'function' }

Would be happy to submit a PR if this looks good to you!
