stdlib `secrets.token_hex()` speeded up 2x

[NewUserHa]

Feature or enhancement

CPython 3.11 is on average 25% faster than CPython 3.10

Therefore hope the python 3.12 stdlibs can get optimized as well, since maybe web could use secrets tokens a lot

import os
t = os.urandom(32)

# Before:
timeit binascii.hexlify(t).decode('ascii') # 215 ns ± 6.7 ns per loop (mean ± std. dev. of 7 runs, 1,000,000 loops each)

# After: 
timeit t.hex() # 91 ns ± 1.6 ns per loop (mean ± std. dev. of 7 runs, 10,000,000 loops each)
