Describe the bug:
Can't use ELASTIC_APM_SERVER_URL = "url:port" when building elastic apm instance from aiohttp app since new url control have been added on Yarl dependent library.

To Reproduce

1. Intall dependencies
2. configure aiohttp web app with global variable ELASTIC_APM_SERVER_URL = "url:port"
3. build ElasticAPM(app) instance app as a aiohttp web app.
4. raises a ValueError from yarl python library because of the format "url:port" not allowed (since yarl 1.13)

Environment (please complete the following information)

• OS: linux
• Python version: 3.12.7
• aiohttp : "3.10.5"
• elastic-apm = "6.23.0"

Additional context
Error:
File "/home/nonroot/venv/lib/python3.12/site-packages/yarl/_url.py", line 1607, in _host_validate\n raise ValueError(\nValueError: Host 'X.X.X.X:8080' cannot contain ':' (at position 11)"

When downgrading yarl to 1.12.1, it's now working again.
