Symlinks not working

### Summary

A symlink to a file is always seen as a directory (symlink to directory works fine).

### System Setup

```markdown
- Android: 13
- Cryptomator: 1.10.3
- Xiaomi Redmi Note 11 phone (HyperOS 1.0.3)
```

### Cloud Type

Google Drive

### Steps to Reproduce

1. With Linux ln, make a symbolic link to a file in the vault (V8 format, Cryptomator Windows 1.14), using either an absolute or relative target pathname;
2. Access the vault in Google Drive from CM Android;
3. CM sees all symbolic links as directories and linked files can't get accessed.

### Expected Behavior

CM Android distinguishes between symbolic link to files and symbolic links to dirs, just like Windows or Linux Desktop version; `mklink` in Windows can work

### Actual Behavior

CM Android does not display symlinked files as such, but as directories; `mklink` in Windows can't create symlinks due to an unknwon device I/O error.

### Reproducibility

Always

### Relevant Log Output

```shell

```

### Anything else?

Created symlinks inside the vault work fine both in Linux and Windows.

*04/11/24 UPDATE*: symlinks to directories does not work properly, too: in fact, CM Android requires a `dir.c9r` file in the symlink directory (where `symlink.c9r` file resides), but this is not required by Desktop editions, whose sanity check signals such situation as an error ("ambiguity" between symlink/directory). Discovered while developing my [pycryptomator](https://github.com/maxpat78/pycryptomator) app - putting a dir.c9r file in the symlink directory by hand let CM Android interpret and resolve correctly the symlink to the target directory, but this is not the expected behavior!
