Nimble Install Fails
I'm having problems with the installation of many packages. Seems to be a problem with the nimble file format.

e.g. `nimble install https://github.com/alehander92/gara`
generates following error message:

```
Downloading https://github.com/alehander92/gara using git

        ... printPkgInfo() failed.

```

I forked the project and changed the nimble file using classic ini file sections and the installation works fine: `nimble install https://github.com/schmidh/gara`

See [schmidh/gara.nimble](https://github.com/schmidh/gara/blob/master/gara.nimble).

(E.g. package `daemonize` works also fine, `nimlsp` not.)

The same is true for new nim projects created with `nimble init`.

```
nimble init nimbleTest -y
cd nimbleTest
nimble dump
