workflow: update renovate config to use haoqunjiang's personal preset

Also moved to `.github/renovate.json` to keep the root directory clean.

Compared with the current config, the new preset:
- Extends `config:recommended` instead of `config:base` ([it's just a
name change, though](renovatebot/renovate#21136))
- Extends `:widenPeerDependencies`
- A more nuanced update strategy for `typescript` in case we are several
minor versions behind
- Groups all Vite packages together for easier management, esp. when
Vite 6 is released
- Separates 0.x versions of packages from the rest so we can deal with
the breaking changes in a more controlled manner. This mainly affects
`esbuild`.
