fix: remove subgraph task (#5)

We don't have a subgraph for solidity empty, so the subgraph tasks fail
with:

```
 Executing task: make subgraph 

Deploying the subgraph...
/bin/sh: 1: cannot create subgraph/subgraph.config.json: Directory nonexistent
make: *** [Makefile:75: subgraph] Error 2

 *  The terminal process "/usr/bin/bash '-c', 'make subgraph'" failed to launch (exit code: 2). 
 *  Terminal will be reused by tasks, press any key to close it. 
```
