Prevents breaking changes with node-fetch 3.0.0 (#67)

fix: installing node-fetch 3.0.0 as a child dependency throws an error `(node:2006) UnhandledPromiseRejectionWarning: Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /[PROJECT-PATH]/node_modules/node-fetch/src/index.js`


### Description

Running `yarn install` and then `yarn build` throws the following error:

```
(node:2006) UnhandledPromiseRejectionWarning: Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: node_modules/node-fetch/src/index.js
require() of ES modules is not supported.
require() of node_modules/node-fetch/src/index.js from node_modules/next/dist/next-server/server/node-polyfill-fetch.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
```

### Changelog

**Changed**

Changed "resolutions" in `package.json` to limit child dependency `node-fetch` to minor versions.
