Show the email for each committee on their respective pages.

### Why?
Not every committee has put its email address in its description on the website.

For example, if I want to reach the study trip committee, I will not find an email to reach them on [their page](https://thalia.nu/committees/49/).

### Current implementation
On each committee page, there is a description of the committee.

### Desired implementation
On each committee page, there is a description of the committee and below the description there is an email address to reach the committee.
