rollup plugin fails on json import

https://github.com/MetaMask/snaps/blob/e95e6709cc3e883582e72994288f3c285ee10d7f/packages/snaps-utils/src/derivation-paths.ts#L2

this line need `with { type: 'json' }` or the rollup plugin fails

```bash
[!] TypeError: Module "file:///Users/hd/code/filsnap/node_modules/.pnpm/@metamask+slip44@3.1.0/node_modules/@metamask/slip44/slip44.json" needs an import attribute of type "json"
```

Open packages/snaps-utils/src/derivation-paths.ts at line 2 and reproduce the failure with the Rollup build that imports @metamask/slip44/slip44.json. Update the import so the JSON module is accepted, then confirm the reported Rollup error no longer occurs.
