1-wiring-up.ipynb file has issues

[Razeen-ud-din]

After the recent datatype changes comment on github I noticed that the file 1-wiring-up.ipynb is not rendering the following cell

`from qualtran import BloqBuilder
from qualtran import QInt

bb = BloqBuilder()
x = bb.add_register('x', QInt(8))

do_nothing = bb.finalize(x=x)

import qualtran.testing as qlt_testing
qlt_testing.assert_valid_cbloq(do_nothing)`

The below error is showing

TypeError: '<=' not supported between instances of 'QInt' and 'int'

can you post the full traceback and some details of your python environment? I can't reproduce this
