Outdated request object in django_moralis_auth

[imperorrp]

The 'request object' in MoralisWeb3/demo-apps/tree/main/django_moralis_auth/web3_auth/views.py is outdated. (See line 32.)

Took quite a while to pinpoint this, but I was getting an authentication error: message expired while trying to incorporate this into a Django project.

Changing the expiration time to anything beyond the present fixes this, however. Recommend updating this.
