Upgrade Starlette version

[zoola969]

Expected Behavior

No dependency conflict

Actual Behavior

New Fastapi version causes dependency versions conflict

Steps to Reproduce the Problem

1. Try to freeze dependencies with Fastapi >= 0.76.0 and gino-starlette
2. Get an error (pip-tools for example)
   

Btw, there are newer versions of starlette: 0.20.*
tiangolo/fastapi#4820
tiangolo/fastapi#4936
So, if you just change ^0.17 to ^0.19, it wont work for long

Specifications

• Python version: 3.10
• GINO version: 1.0.1
• Starlette version: 0.19.1

I'm happy to review any pull requests. Not an active user of starlette myself, it's better to verify everything works.

I don't seem to have the ability to create a PR, but I tested changing to ^.19 and it didn't break any tests.
