Left menu on Docs page does not display text as specified

[Bi0T1N]

Description

• Expected behavior: Menu entry should be ROS/Gazebo Installation
• Actual behavior: Menu entry is Ros/gazebo Installation

Steps to reproduce

1. Go to https://gazebosim.org/docs
2. Notice that the left menu shows "Ros/gazebo Installation"
3. Compare with what is written in index.yaml

[Bi0T1N]

It's not just the single page listed above, it's wrong for all entries with more than one word. To give some more examples:

• Ros 2 Integration instead of ROS 2 Integration
• Spawn Urdf instead of Spawn URDF
• Understanding The Gui instead of Understanding the GUI

It uses its own mechanism for capitalization of the output instead of respecting what is defined in the index.yaml file.

[Bi0T1N]

I'm not an expert in Golang but the casing might come from the strings.Title() function. It's not used directly in gazebosim-web-backend or gz-go but within the go-gorm dependency.
At least the following examples show the same phenomenon that can be observed at the moment:

package main

import (
	"fmt"
	"strings"
)

func main() {
	fmt.Println(strings.Title(strings.ToLower("Migration from Ignition"))) // Migration From Ignition
	fmt.Println(strings.Title(strings.ToLower("Spawn URDF"))) // Spawn Urdf
	fmt.Println(strings.Title(strings.ToLower("Understanding the GUI"))) // Understanding The Gui
}
