[Request]: Ability to type out query in playground

**Is your feature request related to a problem? Please describe.**
In the previous versions of cube and its playground, I was able to construct my GraphQL queries by typing in the editor. This seems to now be removed, which is frustrating given my usual workflow now has been disrupted. I did find that we can type into some obscure pop up, but this is far less usable than before because now its just a RTB instead of giving us the autocomplete features too.

**Describe the solution you'd like**
I'd like to be able to type out the query again as I like to have fine grained control over how and where my query params etc are used.

**Describe alternatives you've considered**
Previous version of the playground had this feature.

**Additional context**
N/A
