Replace U+201C and U+201D quotes with standard ASCII quotation mark in error output.

A small request to get output that currently looks like:

(XID f7p6sm) The domain “${DOMAIN}” already exists in the Apache configuration.

To output like this instead:

(XID f7p6sm) The domain "${DOMAIN}" already exists in the Apache configuration.

As a system administrator, sometimes I need to awk for columns out of logs/api responses and when the quotations being used are U+201C and U+201D quotes, it can be difficult to split versus using standard quotations.
