fix the range of the random weights used in the int8fc test (#41303)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/41303

[NNPI_LOG][D] [KS] convert_base_kernel_ivp.cpp(524): Output Scale 108240.101562
is out of valid range +-(Min 0.000061 Max 65504.000000)!!!
Seems like the weights we are using are too small, thus generating scaling
factors out of the range of fp16 (>65k). I am tentatively increasing this
factor to a higher value to avoid this. (10x bigger)
Also increased max_examples to 100
Test Plan: ran this test
