chore: add typesVersion to core

[rubencarvalho]

Description

Adds typesVersions mapping to @spectrum-web-components/core package.json to improve TypeScript type resolution compatibility, particularly for users with moduleResolution: "node" or older TypeScript versions.

https://www.typescriptlang.org/docs/handbook/declaration-files/publishing.html#version-selection-with-typesversions

Motivation and context

After the monorepo restructure in v1.10.0, some customers using moduleResolution: "node" with skipLibCheck: false reported TypeScript compilation errors when the type resolution chain passes through the core package.

The typesVersions field provides a fallback mechanism for TypeScript to locate declaration files when the standard exports field resolution encounters issues. This improves compatibility across different TypeScript configurations and versions.
From my brief investigation, typesVersions works because it provides explicit path mappings for TypeScript to find .d.ts files, works as a fallback when exports resolution is incomplete and supports older TypeScript versions that don't fully understand exports field. So this seems defensive enough.

Author's checklist

• I have read the CONTRIBUTING and PULL_REQUESTS documents.
• I have reviewed at the Accessibility Practices for this feature, see: Aria Practices
• I have added automated tests to cover my changes.
• I have included a well-written changeset if my change needs to be published.
• I have included updated documentation if my change required it.

---

Reviewer's checklist

• Includes a Github Issue with appropriate flag or Jira ticket number without a link
• Includes thoughtfully written changeset if changes suggested include patch, minor, or major features
• Automated tests cover all use cases and follow best practices for writing
• Validated on all supported browsers
• All VRTs are approved before the author can update Golden Hash

Manual review test cases

• Test with snapshot release
• Create a snapshot release: yarn publish:snapshot
• Install the snapshot in a test project with strict TypeScript settings:

       {
         "compilerOptions": {
           "moduleResolution": "node",
           "skipLibCheck": false
         }
       }

• Import and use SWC components (extend IconBase, use querySelector, etc.)

• Expect: No TypeScript errors about missing HTMLElement or Element properties

• Test with StackBlitz reproduction

• Open the existing StackBlitz reproduction: https://stackblitz.com/edit/vitejs-vite-supsbswo?file=package.json,src%2Fmy-element.ts,tsconfig.json

• Update dependencies to use this PR's changes (via snapshot or branch)

• Run TypeScript type checking

• Expect: TypeScript errors should be resolved
