US: Allow for more data types to be set in data attribute for apps.

### Description

As a < type of user >, I want < some goal > so that < some reason >.

### Acceptance criteria

```nix
data = {
  port = 80;
};
```

Should work with:
```nix
{
  content = 80;
  name = "port";
  path = «derivation /nix/store/52imnkpmhha676k099sdhw954f09aq1n-port.drv»;
}
```

To allow for more flexible use of data. Maybe bools and floats as well.
