IPNS records are validated twice when resolved

[2color]

Background

Currently, the @helia/ipns package relies on the routers abstraction to resolve IPNS record. This allows it to use more than one router to resolve a record, e.g. DHT, PubSub, and delegated routing API.

As it currently stands, the IPNS module handles verification of every record it gets from a router:

helia/packages/ipns/src/index.ts

Lines 425 to 434 in 19bf9ce

	routers.map(async (router) => {
	try {
	const record = await router.get(routingKey, options)
	await ipnsValidator(routingKey, record)
	records.push(record)
	} catch (err) {
	log.error('error finding IPNS record', err)
	}
	})

Additionally, thehelia-delegated-routing-v1-http-api also validates the IPNS record which results in two validations which is unnecessary.

Would be good to add an option to the https://github.com/ipfs/helia-delegated-routing-v1-http-api to avoid verifying the record
