Basic Git clone fails when default branch is not 'main'

[fabjanvucina]

Describe the bug
As the title suggests, cloning a Git repository into a Sandboxe without specifying a branch fails if the default branch for that repository is not 'main'

DaytonaError: "couldn't find remote ref \"refs/heads/main\"

To Reproduce
Steps to reproduce the behavior:

1. Find Git repository with "master" as the default branch
2. Run the following:

await sandbox.git.clone(
    "https://github.com/user/repo.git",
    "workspace/repo"
);

Expected behavior
Default repository branch is dynamically detected.
