fix(sidebar): inherit color from itemgroup/menu (it not provided)

[bence444]

Added optional parameter to the SidebarItemGroupComponent, so it's possibly to create a "simple" sidebar items without dropdowns (e.g. Logout button). Also removed the check it's existence from the verify() function.

Removed the default value of color input, and created a private computed to use in fetchClass().

• In this case if the color is set it'll be the value
• If the color is not set, and a SidebarItemGroupComponent exists, it'll be the group's color
• Otherwise it'll be the SidebarMenuComponent's color, since it's required

<flowbite-sidebar isOpen class="min-h-screen">
    <flowbite-sidebar-menu class="w-64" color="green">
      <flowbite-sidebar-item-group
        isOpen
        title="Group 1"
        color="red">
        <flowbite-sidebar-item>Menu 1</flowbite-sidebar-item>
        <flowbite-sidebar-item color="yellow">Menu 2</flowbite-sidebar-item>
      </flowbite-sidebar-item-group>

      <flowbite-sidebar-item-group
        isOpen
        title="Group 2"
        color="blue">
        <flowbite-sidebar-item>Menu 3</flowbite-sidebar-item>
        <flowbite-sidebar-item color="yellow">Menu 4</flowbite-sidebar-item>
      </flowbite-sidebar-item-group>

      <flowbite-sidebar-item-group
        isOpen
        title="Group 3">
        <flowbite-sidebar-item>Menu 5</flowbite-sidebar-item>
        <flowbite-sidebar-item color="yellow">Menu 6</flowbite-sidebar-item>
      </flowbite-sidebar-item-group>

      <flowbite-sidebar-item>Menu 7</flowbite-sidebar-item>
    </flowbite-sidebar-menu>

    <flowbite-sidebar-page-content class="p-4">
      Hello world!
    </flowbite-sidebar-page-content>
</flowbite-sidebar>

In this example the SidebarItems color's will look like this:

• Menu 1: red - inherited from Group 1
• Menu 2: yellow - directly set
• Menu 3: blue - inherited from Group 2
• Menu 4: yellow - directly set
• Menu 5: primary - inherited from SidebarItemGroup green from SidebarMenu (Edit: somehow i messed up something, it looks good to me)
• Menu 6: yellow - directly set
• Menu 7: green - inherited from SidebarMenu

Just realized that i overcomplicated with the computed.

Also removed the check it's existence from the verify() function.

That was a mistake, and made it back.
