feat: Add distribution-specific dependencies using nfpm overrides

Implements feature #4339 by enhancing the nfpm.yaml.tmpl to use nfpm's built-in
overrides feature for different Linux distributions and package formats.

## Changes Made:

### Enhanced nfpm configuration with overrides:
- **Default**: Debian 12/Ubuntu 22.04+ with WebKit 4.1 dependencies
  - Uses libgtk-3-dev, libwebkit2gtk-4.1-dev, build-essential, pkg-config
- **RPM override**: RHEL/CentOS/AlmaLinux/Rocky Linux with WebKit 4.0 dependencies
  - Uses gtk3-devel, webkit2gtk3-devel, gcc-c++, pkg-config
- **Arch override**: Arch Linux with WebKit 4.1 dependencies
  - Uses gtk3, webkit2gtk-4.1, base-devel, pkgconf

This approach uses nfpm's native override system to automatically select
the correct dependencies based on the target package format, ensuring
that each distribution gets the appropriate WebKit version and package names.

### How it works:
- DEB packages get WebKit 4.1 dependencies (default)
- RPM packages get WebKit 4.0 dependencies (RHEL/CentOS compatibility)
- Arch packages get WebKit 4.1 dependencies with Arch-specific package names

Fixes #4339
