Manual testing steps

1. Build on main
2. Switch to linea-goerli
3. Build on this PR
4. You should be on linea sepolia instead of linea goerli
5. You can add linea goerli by clicking on the navigation button in the wallet and type in: chainlist.org. Connect your wallet and you can look for the network you want to add then click on "add to metamask" button. (I used this RPc url https://59140.rpc.thirdweb.com to add linea goerli)
