Release: Patch 9.0.18

[github-actions]

This is an automated pull request that bumps the version from 9.0.17 to 9.0.18.
Once this pull request is merged, it will trigger a new release of version 9.0.18.
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: Svelte: Fix union types generating invalid labels in argTypes #31980
• 🔧 Maintenance: Telemetry: Add nodeLinker to telemetry #32072
• 🐛 Bug: CLI: Fix Storybook doctor compatibility checks #32077
• 📝 Documentation: Docs: How we develop features and release Storybook #31662
• 📝 Documentation: docs: remove deprecated vscode extension #32078
• 📝 Documentation: Docs: Vue - Remove reference to Volar extension #32079

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

2. Improvements to the Storybook doctor CLI tool to better handle compatibility checks with canary and 0.x versions
3. Enhanced telemetry by adding nodeLinker information to track package manager configurations
4. Documentation updates removing deprecated VSCode extensions and improving feature development guides

All changes are focused on stability and maintenance without introducing breaking changes, making this an appropriate patch release.

Confidence score: 5/5

1. This PR is very safe to merge as it contains only bug fixes, telemetry improvements, and documentation updates
2. The score is 5/5 because all changes are well-tested, properly scoped for a patch release, and fix specific documented issues without introducing new features or breaking changes
3. The following files deserve extra attention:

   • code/lib/cli-storybook/src/doctor/getIncompatibleStorybookPackages.ts - Verifies compatibility check improvements
   • code/core/src/telemetry/get-package-manager-info.ts - Confirms proper nodeLinker detection
