gpui_linux: Set _NET_WM_NAME during X11 window creation (#51899)

#### Context

On X11, the Settings window title displayed as `"Zed â██ Settings"`
instead of "Zed — Settings"`. The em-dash (U+2014) was garbled because
the window creation path only set the legacy `WM_NAME` property (Latin-1
encoded), but never set `_NET_WM_NAME` (UTF-8). Modern taskbars prefer
`_NET_WM_NAME`, so without it they fell back to `WM_NAME` and
misinterpreted the UTF-8 bytes as Latin-1.

`set_title()` already sets both properties, which is why windows that
update their title after creation (like the main workspace) were
unaffected.

The fix adds `_NET_WM_NAME` during window creation, matching what
`set_title()` already does.

#### Closes #51871

#### How to Review

Single change in `crates/gpui_linux/src/linux/x11/window.rs` focus on
the new `_NET_WM_NAME` property being set alongside the existing
`WM_NAME` in `X11Window::new`.
