Bug 274767 – REGRESSION(279341@main): Minibrowser crashes if schema doesn't contain 'color-scheme'

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Diego Pino]

In Playwright, after 279341@main, there are several tests failing with the following error:

```
	<launching> /home/pwuser/playwright-browsers/browser_patches/webkit/pw_run.sh --inspector-pipe --user-data-dir=/tmp/playwright-test-DxSUjl about:blank

	[pid=369127] finished temporary directories cleanup
```

It's necessary to check whether the schema contains 'color-scheme' before calling `g_settings_set_enum(interfaceSettings, "color-scheme")`.
