Documentation: 3scale title trait invalid when generating documentation

[gansheer]

The document generation make command make generate generates the docs/modules/ROOT/nav.adoc file with inside :

...
 // Start of autogenerated code - DO NOT EDIT! (trait-nav)
** xref:traits:3scale.adoc[3Scale]
** xref:traits:affinity.adoc[Affinity]
...

The bug : 3Scale should be 3scale (small 's'): https://www.3scale.net/

The generation command use for the title:

• the following flag in trait comments:
  

  camel-k/addons/threescale/3scale.go

  Line 36 in 4024c6a

  // +camel-k:trait=3scale.

• the generation following code:
  

  camel-k/cmd/util/doc-gen/generators/traitdocgen.go

  Lines 147 to 154 in 4024c6a

  	func traitNameFromFile(file string) string {
  	name := strings.TrimSuffix(file, ".adoc")
  	name = strings.ReplaceAll(name, "trait", "")
  	name = strings.ReplaceAll(name, "-", " ")
  	name = strings.Trim(name, " ")
  	name = cases.Title(language.English).String(name)
  	return name
  	}

Adding a way to override the default generation code for a specified code would fix the bug and help give mode flexibility.
