HTTP 401 | Trailing slash in API endpoints

[yudikubota]

Steps to reproduce

1. make a request to https://mainnet.infura.io/v3/<PROJECT_ID>/

What is happening

HTTP 401 Unauthorized

What is expected

I think Infura API should handle the trailing slash as it cannot be part of PROJECT_ID and it's very common to add a trailing slash automatically.
