Support `file://` paths in `component.yml:spec.source.uri`

### Describe the Bug

Specs for component.yml say it supports anything from HashiCorp/go-getter but I am unable to use a local path.

```yml
spec:
source:
uri: ./
```

```bash
kevin@Kevins-Laptop aurora-postgres % atmos vendor pull -c spacelift
Pulling sources for the component 'spacelift' from 'file:///Users/kevin/code/sts-devops/components/github-repositories' into '/Users/kevin/code/sts-devops/components/spacelift'

error downloading 'file:///Users/kevin/code/sts-devops/components/github-repositories': destination exists and is not a symlink
```

### Expected Behavior

I would like to use a local file path because we are using Atmos features like mixin but we are not using a remotely hosted module/component.

### Steps to Reproduce

```yml
spec:
source:
uri: ./
```
