Add support for partial clones

Hello,

I would like to use treeless clones or blobless clones in my GitHub Actions workflow, but Source Link does not support it.

More info https://github.blog/2020-12-21-get-up-to-speed-with-partial-clone-and-shallow-clone/

My workflow

``` yml
steps:
- name: Checkout
uses: actions/checkout@v4
with:
fetch-depth: 0 # (no history limit)
filter: tree:0

- name: Build
run: dotnet build
```

My build fails due to Source Link not supporting this configuration.
