Release: Prerelease 10.3.0-alpha.7

[github-actions]

This is an automated pull request that bumps the version from 10.3.0-alpha.6 to 10.3.0-alpha.7.
Once this pull request is merged, it will trigger a new release of version 10.3.0-alpha.7.
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:

• 🐛 Bug: Next.js: Handle legacyBehavior prop in Link mock component #33862 (will also be patched)
• 🐛 Bug: Core: Require token for websocket connections #33820 (will also be patched)
• 🐛 Bug: Preact: Support inferring props from component types #33828
• 🏗️ Build: Build: Lower the number of parallel dts bundle generation at prod #33866
• 📝 Documentation: Docs: Adjust builder API snippet #33852
• 📝 Documentation: Docs: Point monorepo links to next branch #33799
• 📝 Documentation: Docs: Fix build command and typo in main config build #33816
• 📝 Documentation: Docs: Fix broken CSF doc links #33793

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
