Correct the email address for development email list subscription on the project website

The email address for development email list subscription is not correct on 2 webpages:

1. Project webpage:
https://mnemonic.incubator.apache.org/develop/
The incorrect subscription email on this webpage is:
list-subscribe@mnemonic.incubator.apache.org

2. Wiki webpage:
https://cwiki.apache.org/confluence/display/MNEMONIC/How+to+Contribute+to+Mnemonic
The incorrect subscription email on this webpage is:
subscribe-dev@mnemonic.incubator.apache.org

Both of these email addresses do not exist, I sent subscription email but the system cannot deliver to them. They need to be replaced by the correct subscribe email address (I can subscribe email list with this address): dev-subscribe@mnemonic.incubator.apache.org
