Fix download failing on FIPS machines (#7698)

### Description
This PR fixes downloads failing on FIPS enabled machines due to insecure
MD5 hashing. The two solutions are to disable MD5 hashing (SHA1 is
allowed and faster), or use the `usedforsecurity=False` flag. This PR
uses the second method. However, the `usedforsecurity` flag only works
for Python 3.9 and later (which was accounted for). Let me know if you
have a better implementation to solve this issue.

The error thrown on FIPS enabled machine is:
```ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for FIPS```
