fixup http01_example.py (#10285)
it looks like https://github.com/certbot/certbot/pull/10098 introduced a
couple bugs into this file:

1.
[RSAPrivateKeys](https://cryptography.io/en/latest/hazmat/primitives/asymmetric/rsa/#cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey)
don't have a `public_bytes` method
2. `cryptography.x509` wasn't imported and
[load_pem_x509_certificate](https://cryptography.io/en/latest/x509/reference/#cryptography.x509.load_pem_x509_certificate)
takes bytes, not a string

i think avoiding this is unfortunately difficult as this file has no
tests, but it was useful for me just now when testing
https://github.com/certbot/certbot/pull/10283 so i wanted to fix it up

i also changed the script to initially create the account without an
email address as the fake@example.com email causes registration with
LE's staging server to fail early in execution

with the changes in this PR changes, if you:

1. change the value of
[DOMAIN](0075104805/acme/examples/http01_example.py (L57))
to a domain pointing at your machine
2. as root, activate your certbot dev environment, and run `python
acme/examples/http01_example.py `

it will fail late in the script with:
```

if you also change [this email

to a valid email address, the script will run successfully
