Update node-fetch dependency to v3.x.x

[akhmadullin]

Hi.

node-fetch released new major version - 3.0.0

https://github.com/node-fetch/node-fetch/releases/tag/v3.0.0

Are you planning to update node-fetch dependency to ^3.x.x in fetch-mock?

node-fetch@3 is ES modules only, so it would require updating this entire library from commonjs. Probably something I'll look at after addressing the ling backlog of other issues

Hi @wheresrhys,

are there any news regarding node-fetch@3 compatibility?

Because of the * peerDependencies version field, users of fetch-mock can't see something is wrong when installing node-fetch@3.x.x:

fetch-mock/package.json

Lines 48 to 50 in 1bdac54

	"peerDependencies": {
	"node-fetch": "*"
	},

Are you open to a PR updating the node-fetch peerDependencies version field to be < 3.0.0 for example? This could be released as a patch IMO.

   "peerDependencies": {
-    "node-fetch": "*"
+    "node-fetch": "< 3.0.0"
   },
