Update to node-fetch v3

[peter-evans]

There seems to be some breaking changes to update to v3. There is an upgrade guide here.

Dependabot cannot auto-bump: #84

If you would like to help with this issue please make the minimum changes necessary to upgrade.

Perhaps just update to node 18, native fetch and all?

@jbergstroem Unfortunately, node-based GitHub actions can only use Node 12 and 16 at the moment. But if 18 becomes available, I will consider that option. Thank you!
