Molecule config file in {project}/.config/molecule/config.yml not found

### Prerequisites

- [X] This was not already reported in the past (duplicate check)
- [X] It does reproduce it with code from main branch (latest unreleased version)
- [X] I include a minimal example for reproducing the bug
- [X] The bug is not trivial, as for those a direct pull-request is preferred
- [X] Running `pip check` does not report any conflicts
- [X] I was able to reproduce the issue on a different machine
- [X] The issue is not specific to any driver other than 'default' one

### What happened

**ISSUE:**
Molecule settings put into `{PROJECT_DIR}/.config/molecule/config.yml` are not found or used, but they are if I move `.config/molecule/.config.yml` to my user home directory.

**EXPECTATIONS:**
Molecule [documentation](https://ansible.readthedocs.io/projects/molecule/configuration/#prerun) states that we can put configurations into `{PROJECT_DIR}/.config/molecule/config.yml` or into `~/.config/molecule/config.yml` So both options should work.

**EXAMPLE:**
My example directory structure:
```
$ tree -a my_project/
my_project/
├── .config
│ └── molecule
│ └── config.yml
└── roles
└── somerole
└── molecule
└── default
├── converge.yml
├── create.yml
├── destroy.yml
└── molecule.yml
```

Here are the contents of `config.yml`:
```
---
driver:
name: docker
```

Here's what I see if I configure using `~/.config/molecule/config.yml` - it finds the file and the settings are used, this is good:
```
$ molecule converge
INFO Found config file /home/my_user/.config/molecule/config.yml
```

When I remove that `~/.config/molecule/config.yml` and only have `./my_project/.config/molecule/config.yml`it does not read these settings. I tried moving the .config directory to all different levels within the project dir with no luck.

**POSSIBLE SOLUTION**
I believe the issue lies in the `find_vcs_root` function in the file [util.py](https://github.com/ansible/molecule/blob/stable/6/src/molecule/util.py)

Adding `, ".config"` into the dirs variable in the `find_vcs_root` function definition line seems to resolve the issue for me:
```
def find_vcs_root(location="", dirs=(".git", ".hg", ".svn", ".config"), default=None) -> str:
```

I wanted to submit this as a PR as it seems fairly trivial but I am having issues getting my environment configured correctly. I apologize in advance if I did not contribute this exactly to the guidelines.

### Reproducing example

_No response_

Start in src/molecule/util.py at find_vcs_root and trace how molecule converge discovers configuration files. Run the provided project layout with molecule converge, then inspect existing tests for configuration discovery. Done means a project-local .config/molecule/config.yml is found and used while the home-directory configuration continues to work.
