Python cannot be found on unsupported architectures

[lengau]

On unsupported architectures (e.g. riscv64), uv cannot find the local Python because the machine is not in a list of known items:

error: No interpreter found in virtual environments, managed installations, or system path

If the platform_machine of a local Python matches the machine type from uname, uv should also accept it.

Thanks for the report! It seems fine to just add this to the list.

Added in #8660

Thank you so much!
