Typescript's type aliases (`type X = thing`) can refer to basically
anything, which makes it hard to write an automatic document formatter
for them. Interfaces on the other hand are only object, so they play
much nicer with docs. Currently, object-flavoured type aliases don't
really get expanded at all on our docs site, which means we have a bunch
of docs content that's not shown on the site.
This diff introduces a lint rule that forces `interface X {foo: bar}`s
instead of `type X = {foo: bar}` where possible, as it results in a much
better documentation experience:

This PR replaces our `console.log` with `nicelog` so that I can more
easily grep for errant console.logs.
### Change Type
- [x] `internal` — Any other changes that don't affect the published
package (will not publish a new version)
We make use of this `exec` function for the new huppy bot. For that, I
needed to support a couple of extra use-cases: extending the `env` used
to evaluate a command, and prefixing the command output with a string.
In use, these look something like this:
```ts
await exec('my', ['command'], {
env: {HELLO: 'world'},
...prefixOutput('my prefix'),
})
```
