Issues with peer dependencies

[troubleshooting section]: https://iles-docs.netlify.app/faqs/troubleshooting

- [x] I have read the __[troubleshooting section]__ before opening an issue.
- [x] I have tried upgrading `iles` and `vite`.

### Description 📖

After bumping the dependencies, issues with peer dependencies are found by pnpm.

I think `@islands/feed` needs to update the peer dependency version and `iles` needs to bump its dependencies.

### Reproduction 🐞

Run `ncu`, `pnpm i` and `pnpm typecheck` in https://github.com/ouuan/iles-blog.

`pnpm i` shows:

```
 WARN  Issues with peer dependencies found
.
├─┬ @islands/feed 0.8.0
│ └── ✕ unmet peer iles@^0.8: found 0.9.0
└─┬ iles 0.9.0
└─┬ unplugin-vue-components 0.21.2
└─┬ unplugin 0.7.2
└── ✕ unmet peer vite@"^2.3.0 || ^3.0.0-0": found 4.0.3 in iles
```

~~`pnpm typecheck` shows:~~ (see edit log) It turns out that the type check error was caused by https://github.com/doesdev/rollup-plugin-analyzer not specifying rollup version in `package.json` and using rollup 2, which is not related to iles, and the peer dependency warnings are harmless. But still love to see updated dependencies with the peer dependency warning resolved :)
