1.0.13 breaks build

Getting an error during build:

```
Error message
Could not import plugin:
/opt/build/repo/node_modules/@algolia/netlify-plugin-crawler/src/index.ts:1
import type { NetlifyPluginOptions, NetlifyPluginUtils } from '@netlify/build';
^^^^^^

SyntaxError: Cannot use import statement outside a module
```

I think upgrading `node-fetch` to a version >2 led to this problem since version >=3 doesn't support CJS. We had to downgrade to 1.0.12.

The version should either but adjusted accordingly (not a minor version) or node-fetch should be downgraded.

Start by reproducing the build failure with version 1.0.13 and compare its node-fetch dependency with version 1.0.12. Inspect the plugin entry at node_modules/@algolia/netlify-plugin-crawler/src/index.ts and verify that the chosen versioning or dependency change allows the Netlify build to complete without the CJS/ES module error.
