security/py-certbot: Revert "added missing runtime dep py-typing-extensions"

This reverts commit 247856f790fa0917e0461097cd6ce64493a6f447.

According to backtrace in commit message of commit 247856f790fa,
typing_extensions is imported from
site-packages/OpenSSL/crypto.py. And it belongs to not certbot but
pyOpenSSL. So devel/py-typing-extensions should be added to
RUN_DEPENDS of security/py-openssl that is indirect runtime dependency
of certbot.
