lib: narrow ReadableStreamBYOBRequest.view return type to Uint8Array

[Jah-yee]

Description

Follow WHATWG streams spec update: whatwg/streams#1367

ReadableStreamBYOBRequest.view is always constructed as a Uint8Array, and the specification will be updated to enforce this. This changes the documented return type from ArrayBufferView to Uint8Array.

Fix

Changed the JSDoc type annotation for view getter from @type {ArrayBufferView} to @type {Uint8Array} in lib/internal/webstreams/readablestream.js.

Relation to #62958

This PR replaces #62958, which was closed after the commit message lint check failed. The commit message was corrected (per feedback from @MattiasBuelens) and resubmitted as this new PR with the fix already applied.

Fixes #62952

Hi @MattiasBuelens, thank you for your review on #62958! 👋

This PR replaces #62958 with the corrected commit message (per your feedback on the line-length lint issue — the commit message was adjusted accordingly).

The change is identical: a 1-line JSDoc type narrowing from ArrayBufferView to Uint8Array, following the WHATWG streams spec update.

The CI checks were cancelled (not failed) and appear to be pending. Could you please review this PR when you have a moment? Happy to address any feedback.

Also tagging @gurgunday — thank you for the earlier feedback on #62958 as well! 🙏
