## Message

```
Add support for Netpbm image previews (#54256)

This PR adds support for rendering **Netpbm** image formats (`.pbm`,
`.ppm`, `.pgm`) within Zed's built-in image viewer.

These formats are particularly useful for projects that want minimal
external dependencies, a common scenario in academic environments and
low-level graphics programming.

Since the underlying `image` crate and `GPUI` already provide support
for these codecs, this change explicitly exposes the `Pnm` variant
within `gpui::ImageFormat` by mapping it to `image::ImageFormat::Pnm`.

## Screenshots/Examples

Below is an example of `.pbm`, `.ppm`, and `.pgm` files being rendered
correctly in the image preview (images taken from

/>



Release Notes:
  - Added support for PNM image previews (`.pbm`, `.ppm`, `.pgm`).
```
