Allow dev to choose navbar color light/dark (class)

[cavasinf]

With the current state,
Navbar color is hard coded (navbar-light):

TablerBundle/templates/layout.html.twig

Line 25 in e5a0366

<header class="navbar navbar-expand-md navbar-light d-print-none">

TablerBundle/templates/layout.html.twig

Line 65 in e5a0366

<div class="navbar navbar-light">

We need to allow dev to choose between navbar dark or light.

⚠️ Changes must be done with layer vertical and horizontal ⚠️

And in line

TablerBundle/templates/layout.html.twig

Line 65 in e5a0366

<div class="navbar navbar-light">

When I set body class="theme-dark" then the navbar is dark, even if it has the class navbar-light.

theme-dark override every -light class configuration.

For me it is a normal behavior, do you see something wrong with that ?

What I want to do is:
Horizontal :

• Dark: https://preview.tabler.io/layout-navbar-dark.html?theme=light
• Light: https://preview.tabler.io/layout-horizontal.html?theme=light

Vertical:

• Dark: https://preview.tabler.io/layout-vertical.html?theme=light
• Light: https://preview.tabler.io/layout-vertical-transparent.html?theme=light

Vertical condensed:

• Light: https://preview.tabler.io/layout-combo.html?theme=light
• Dark: No demo from Tabler
