Expected behavior

"When the --idf-mirror parameter is used, priority should be given to the address specified in the parameter."

Actual behavior (suspected bug)

If the https:// prefix is added, the fastest mirror will be selected automatically; if the https:// prefix is omitted, local resources will be selected instead of online resources.

Steps to reproduce the behavior

Here is my environment setup, though the reverse implementation could also be possible:
Located in China, testing shows that the Chinese mirrors have lower latency and should naturally be preferred. However, since the preference is to use GitHub, the parameters --idf-mirror [https://github.com](https://github.com) and --idf-mirror github.com were added.
