chore: add package support metadata

[YfengJ]

Summary

• add the package homepage pointing to the repository README
• add the package bugs URL pointing to the repository issues page

Why

The published npm metadata currently exposes the repository and license, but does not include homepage or bugs fields. Adding these fields makes the package support links easier to discover from npm and other package tooling.

Current npm metadata checked with:

npm view rsbuild-plugin-ejs@latest name version repository homepage bugs license --json

{
  "name": "rsbuild-plugin-ejs",
  "version": "2.0.1",
  "repository": "https://github.com/rstackjs/rsbuild-plugin-ejs",
  "license": "MIT"
}

Validation

• node -e "const p=require('./package.json'); if(p.homepage !== 'https://github.com/rstackjs/rsbuild-plugin-ejs#readme') throw new Error('bad homepage'); if(!p.bugs || p.bugs.url !== 'https://github.com/rstackjs/rsbuild-plugin-ejs/issues') throw new Error('bad bugs url'); console.log(JSON.stringify({homepage:p.homepage, bugs:p.bugs}, null, 2));"
• pnpm install --frozen-lockfile --ignore-scripts
• pnpm run lint
• pnpm run build
• pnpm run test
• npm pack --dry-run --ignore-scripts --json .
• git diff --check
