Bug: Title tag including "/" breaks asyncapi schema generation/hosting

[oyste]

Describe the bug
When using publisher/subscriber decorators with a title prop on redis fastapi plugin routers the asyncapi schema generation can fail. This happens specifically when I use "/" in a title name and leads to a blank asyncapi webpage.

How to reproduce
This code fails:

from fastapi.responses import HTMLResponse
from faststream.asyncapi import get_app_schema, get_asyncapi_html
from faststream.redis.fastapi import RedisRouter

router = RedisRouter(url=REDIS_URL, prefix="/websocket", tags=["websocket"])

@router.publisher("datastream", title="websocket/datastream", schema=WsMessageDatastreamResponse)
@router.subscriber("datastream", title="websocket/datastream")
async def datastream_func(auth: WsMessageDatastream):
    pass

@router.get("/new_docs")
async def asyncapi_ui_new() -> HTMLResponse:
    return HTMLResponse(get_asyncapi_html(get_app_schema(router), expand_message_examples=False))

however swapping "/" to ":" makes everything work:

@router.publisher("datastream", title="websocket:datastream", schema=WsMessageDatastreamResponse)
@router.subscriber("datastream", title="websocket:datastream")
async def datastream_func(auth: WsMessageDatastream):
    pass

Expected behavior
No blank webpage when using "/" in a pubsub decorator title.

Observed behavior
Blank Webpage

Screenshots
If applicable, attach screenshots to help illustrate the problem.

Environment
Running FastStream 0.5.23 with CPython 3.12.5 on Linux

Additional context
Could probably be fixed with a regex check somewhere.

It will be nice if there is not an empty page, but a description of the error - asyncapi/asyncapi-react#1048
