VersionedFastAPI causes all OPTIONS requests to return a 405

[RA-Zagros]

Describe the bug When using VersionedFastAPI all OPTIONS requests return a 405.

app = FastAPI(title='APP NAME')
APP_VERSION = "1.1.1"
app.add_middleware(
    CORSMiddleware,
    allow_origin_regex='https?://.*',
    allow_credentials=True,
    allow_methods=['*'],
    allow_headers=['*'],
)
app.include_router(api_router_v1_0, prefix=config.API_V1_STR)
app.include_router(api_router_v1_1, prefix=config.API_V1_STR)
app = VersionedFastAPI(app)

To Reproduce Steps to reproduce the behavior:

1. initialize app using VersionedFastAPI
2. make a request that requires CORS options
3. view response details
4. returns a 405

Expected behavior Options request to pass as expected

I had to add the middleware after Declaring the VersionedFastAPI. So this should hopefully fix it:

app = FastAPI(title='APP NAME')
APP_VERSION = "1.1.1"
app.include_router(api_router_v1_0, prefix=config.API_V1_STR)
app.include_router(api_router_v1_1, prefix=config.API_V1_STR)
app = VersionedFastAPI(app)
app.add_middleware(
    CORSMiddleware,
    allow_origin_regex='https?://.*',
    allow_credentials=True,
    allow_methods=['*'],
    allow_headers=['*'],
)
