component.md : Component Naming Conventions better consistency

[MachinisteWeb]

Hi everybody. You will find in this PR about Component Naming Conventions Guide part 4 points I propose to update:

1. TitleCase
   There is one « Title case » term so to follow all others I change it into « TitleCase »

2. Case vs Cased
   In first part and old second part version you used kebab-cased-component with letter « d ».
   In second part you not use « d ». I think it's a better choice to kept consitency accross naming

3. Opened and Closed tag in exemple
   I know it's possible to say « there is too verbose » but you have not already explain that is possible to use self-closed format <my-component /> when you use following example

   <kebab-cased-component />
   
   <camel-cased-component />
   <camelCasedComponent />
   
   <title-cased-component />
   <titleCasedComponent />
   <TitleCasedComponent />

   So there is two way:

   1. Use full tag declaration (in this PR)
   2. Explain more sooner that is possible to use self closed way (not in this PR)

4. Space
   I have add a space in self-closed format to respect what you have done in part 3.

Thanks! I made one tiny change to remove the space you added before the end of the self-closing component, but otherwise I like the changes. 🙂 Those previous spaces were before the end were something I missed from another contributor, but I really appreciate your attention to detail!
