Add libxcb-cursor0 to Linux dependencies for Qt 6.5 and up

[IgKh]

Starting Qt 6.5.0, the XCB platform plugin for Linux/X11 also depends on xcb-cursor0 at runtime, logging as much if the compiled application is started without it being present:

from 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin. 
Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

To resolve this in cases where the application needs to be run within the actions workflow, this PR add the requisite Ubuntu package to the dependency packages installed by the action.

Hi! I think we can keep dependencies const but change it to string[]
to avoid error-prone string manipulation. Example code:

const test = (version: number) => {
    const dependencies = [
        "build-essential",
    ]

    if (version > 42) {
        dependencies.push("libxcb-cursor0")
    }

    console.log(`Installing ${dependencies.join(" ")}`)
}

test(41);
test(43);

Thanks @pzhlkj6612! I've applied your suggestion.

Looks good to me.

Found the possible corresponding commit in Qt 6.5.0 Release Note:
