chore: fix unplugin-react repository metadata

[snkk2x-collab]

Summary

• update @arco-plugins/unplugin-react repository metadata to use the public HTTPS Git URL
• correct repository.directory from the stale packages/plugin-unplugin-react path to the actual packages/unplugin-react package path

Why

The package currently points at git@github.com:arco-design/arco-plugins.git, which requires SSH, and its source repository.directory points at packages/plugin-unplugin-react, which does not exist in this repository. The package source lives in packages/unplugin-react.

Validation

• node -e "const p=require('./packages/unplugin-react/package.json'); if (p.repository.url !== 'git+https://github.com/arco-design/arco-plugins.git') throw new Error(p.repository.url); if (p.repository.directory !== 'packages/unplugin-react') throw new Error(p.repository.directory); console.log(JSON.stringify(p.repository))"
• git diff --check
• git ls-remote https://github.com/arco-design/arco-plugins.git HEAD
• from packages/unplugin-react: pnpm dlx npm@10.9.4 install --ignore-scripts --package-lock=false --workspaces=false
• from packages/unplugin-react: pnpm dlx npm@10.9.4 run build --workspaces=false
• from packages/unplugin-react: pnpm dlx npm@10.9.4 pack --dry-run --workspaces=false

Notes

I also tried the repository Yarn install, but the bundled Yarn Berry script fails locally on Node 24 while applying the TypeScript patch with (0 , QO.isDate) is not a function. I used package-level npm validation instead and did not change dependencies or lockfiles.
