Release: Prerelease 8.6.0-alpha.3

[github-actions]

This is an automated pull request that bumps the version from 8.6.0-alpha.2 to 8.6.0-alpha.3.
Once this pull request is merged, it will trigger a new release of version 8.6.0-alpha.3.
If you're not a core maintainer with permissions to release you can ignore this pull request.

To do

Before merging the PR, there are a few QA steps to go through:

• Add the "freeze" label to this PR, to ensure it doesn't get automatically forced pushed by new changes.
• Add the "ci:daily" label to this PR, to trigger the full test suite to run on this PR.

And for each change below:

1. Ensure the change is appropriate for the version bump. E.g. patch release should only contain patches, not new or de-stabilizing features. If a change is not appropriate, revert the PR.
2. Ensure the PR is labeled correctly with one of: "BREAKING CHANGE", "feature request", "bug", "maintenance", "dependencies", "documentation", "build", "unknown".
3. Ensure the PR title is correct, and follows the format "[Area]: [Summary]", e.g. "React: Fix hooks in CSF3 render functions". If it is not correct, change the title in the PR.
   • Areas include: React, Vue, Core, Docs, Controls, etc.
   • First word of summary indicates the type: “Add”, “Fix”, “Upgrade”, etc.
   • The entire title should fit on a line

This is a list of all the PRs merged and commits pushed directly to next, that will be part of this release:

• ✨ Feature Request: Preview: Add globals to extract() #30415 (will also be patched)
• 🐛 Bug: Core: Fix invalid Websocket termination #30408
• 📦 Dependencies: Core: Improve type compatibility with React 19 #30031
• 📝 Documentation: Docs: Play function updates to the canvas example #30365 (will also be patched)
• 🏗️ Build: Build: Added additional react resolutions for next 15 or above sandboxes. #30372
• 🏗️ Build: Build: Update CircleCI configuration to remove build-sandboxes job #30360
• 📝 Documentation: Docs: Update MIGRATION.md #30409
• 🏗️ Build: Build: Fix missing tag in registry command #30400
• 📝 Documentation: RNW-Vite: Document framework options #30380 (will also be patched)

If you've made any changes doing the above QA (change PR titles, revert PRs), manually trigger a re-generation of this PR with this workflow and wait for it to finish. It will wipe your progress in this to do, which is expected.

Feel free to manually commit any changes necessary to this branch after you've done the last re-generation, following the Make Manual Changes section in the docs, especially if you're making changes to the changelog.

When everything above is done:

• Merge this PR
• Follow the run of the publish action
