[11.0 P5] Blazor Preview 5 QuickGrid updates

[guardrex]

Fixes #37102

Daria ...

• We'll be able to merge this as soon as we have the coverage worked out. I've commented-out the release notes coverage for now, and the reference content is all under 11.0 monikers.
• I may have missed some public API that you want to cover. I think thus far that this only has QueryParameterNamePrefix and GetPageUrl. Is there more API to call out?
• The diff might be a bit hard to read because of the versioning changes. You might have better luck looking at it with the internal review article.
• It's FRIDAY! 🎉 Woot! 🍻 ... and perhaps late in the day where you are. Please feel free to wait until early next week to review. However, please don't wait too long because I'll be placing new PRs that will add content to the release notes. I like to structure PRs as best I can to avoid merge conflicts 👹😄 whenever possible.

Pull request overview

Adds .NET 11 Preview 5 QuickGrid SSR/URL-based navigation coverage to the QuickGrid reference article (under >= aspnetcore-11.0 monikers) and stages release-notes content (currently HTML-commented) for Preview 5 release day.

Changes:

• Adds new 11.0-monikered sections to quickgrid.md covering URL-based pagination, multiple grids on the same page, title-based sort identification, and the EnableUrlBasedQuickGridNavigationAndSorting AppContext switch.
• Reworks moniker fencing around existing "Sort by column," "Page items," and "Open and return from a details page" sections so legacy guidance remains for < aspnetcore-11.0.
• Drafts a (commented-out) Preview 5 release-notes blurb in aspnetcore-11/includes/blazor.md summarizing the same QuickGrid changes.
