Missing dependency in docs (pango)

**Problem**

I can't run example-projects with `dx serve` on my machine.

**Steps To Reproduce**

Steps to reproduce the behavior:
- `dx serve` under [file-explorer](https://github.com/DioxusLabs/dioxus/tree/main/example-projects/file-explorer) and similar error with [wifi-scanner](https://github.com/DioxusLabs/dioxus/tree/main/example-projects/wifi-scanner)

**Expected behavior**

Be able to run example projects.

**Screenshots**

Start by locating the documentation for running the file-explorer and wifi-scanner examples with `dx serve`, then compare its setup instructions with the pango, GDK, libsoup, and ATK errors shown here. Update the relevant dependency guidance so a reader can install the required system libraries and run the examples successfully.
