This is a problem of urllib3 (1.25). Workaround is to use older version of it:

pip install -U "urllib3<1.25"

I think it's a bad idea to use unsecure download. I recommend to try:

pip install pyppdf

then in the code first use:

import pyppdf.patch_pyppeteer

that would apply the patch and nothing more is required to do (see this for details).

This is a problem of urllib3 (1.25). Workaround is to use older version of it:
pip install -U "urllib3<1.25"

this works for me.

but

ERROR: pyppeteer2 0.2.2 has requirement urllib3<2.0.0,>=1.25.8, but you'll have urllib3 1.24.3 which is incompatible.
