Action fails: Cannot find detached HEAD ref in "grafted, HEAD, tag: x.x.x"

### Contributing guidelines

- [X] I've read the [contributing guidelines](https://github.com/docker/metadata-action/blob/master/.github/CONTRIBUTING.md) and wholeheartedly agree

### I've found a bug, and:

- [X] The documentation does not mention anything about my problem
- [X] There are no open or closed issues that are related to my problem

### Description

Since version v5.1.0, the action fails with the following error whenever a specific git tag is checked out in combination with using `context: git`:
```
Error: Cannot find detached HEAD ref in "grafted, HEAD, tag: 1.0.0"
```

The issue does not exist with version v5.0.0 of the action. I also can't reproduce it when checking out the default branch or any other branch. It only seems to be broken for tags.

### Expected behaviour

The action completes without any issues and provides the expected tags for the image.

### Actual behaviour

The action fails with the following error message:

```
Error: Cannot find detached HEAD ref in "grafted, HEAD, tag: 1.0.0"
```
