Add support for host name aliases in SSH config

Original issue: https://github.com/demystifyfp/FsToolkit.ErrorHandling/issues/45#issuecomment-491184311

After downloading the [1.1.1 nuget package](https://www.nuget.org/packages/FsToolkit.ErrorHandling), extracting, and running `sourcelink print-json`, the URL generated is incorrect.

```bash
sourcelink print-json FsToolkit.ErrorHandling.TaskResult.pdb
{"documents":{"/Users/tamizhvendan/DemystifyFpWorks/FsToolkit.ErrorHandling/*":"https://demystifyfp/raw/demystifyfp/FsToolkit.ErrorHandling/1c752129694c21842af13da041ec4def9a152327/*"}}
```

The package maintainer @demystifyfp is using a git scheme for their remote.

```bash
git remote -v
origin git@demystifyfp:demystifyfp/FsToolkit.ErrorHandling.git (fetch)
origin git@demystifyfp:demystifyfp/FsToolkit.ErrorHandling.git (push)
```

Is there a bug here?

Do we need to configure something specific to support this? If so can we update documentation or make it more accessible?
