Too short timeout for fetching schema

[azatoth]

Describe the bug
The current timeout for when fetching a schema from remove host can sometime be way too short and resulting in the application fails over and over.

To Reproduce
Used commandline:

$ datamodel-codegen --url "https://lldev.thespacedevs.com/2.3.0/schema" --input-file-type openapi --output "src/thespacedevs_api.py" --snake-case-field --use-default --force-optional

most often than not drops a python exception slug with httpx.ReadTimeout: The read operation timed out as the error:
