Regexp problem if there is no comment in front of the image path

Hi !

Image comment v 1.1.0, Debian 12, VScode 1.93.0, C++ code

I always have the following error "Image Comments Could not find image"

I tried local and canonical paths, jpeg, png ;(

Have I missed apt-get install a lib?

```c++
// *****************************************************************************
//! \brief bla bla
//! [/home/qq/Bureau/foo.png]
// *****************************************************************************
struct Foo { ...
```

And there is no display and no message error with the following comment:

```c++
// [/home/qq/Bureau/foo.png]
struct Foo { ...
```

No source files or tests are named. Start by reproducing the issue in the Image Comments VS Code extension with the two C++ comment examples and then trace the image-path handling from the extension entry point. Done means the image path is handled consistently when preceded by documentation comments and when used directly.
