Remove "Description" field from Stream Overview Page

[tellistone]

As of Graylog 6.1, the stream description field is shown in-line beneath the stream name.

However, it is still possible to enable the description field. This results in a very janky view where the description is shown twice:

We should remove the option to include the description field in this table, since it is already included.

Should we just remove the field, or should we not display the inline description when the field is selected?

I'd favor just removing the description field as something the user can toggle - its simpler for us to implement, and the description field formatting actually doesn't cope as well with long description - I can't see an advantage to allowing the user to toggle the field at all.
