Fix typos in ENSv2 readiness guide

- Fix grammar: "just update" → "just updating"
- Replace "according" with "appropriate" for better clarity
- Fix typo: "will introduction" → "will introduce"
- Fix grammar: "an integrations" → "an integration"
- Fix localhost URL to use relative path

 ## CCIP Read
 
-Already with ENSv1 it is possible to delegate resolution from Ethereum Mainnet to an L2 or completely offchain with [CCIP Read as specified in ERC-3668](http://localhost:5173/learn/ccip-read#layer-2--offchain-resolution).
-All libraries mentioned above already implement CCIP Read. That being said, not all integrations do it properly. Since ENSv2 will introduction the option to store a name on Ethereum Mainnet, Namechain or any other supported L2, support for CCIP-read will be fundamental.

 ### Test
 
-To test if an integrations properly implements CCIP Read, one can simply try to resolve `test.offchaindemo.eth` which should return address: `0x779981590E7Ccc0CFAe8040Ce7151324747cDb97`
