Add line numbers about component-party.dev

[matschik]

If we do that, there will be a war with format/linting config to have their favorite framework having the less nb of lines as possible. For example, people will abuse of one liners or using ternary syntax to optimize nb of lines instead of optimizing clear comparison between framework's snippets. Component Party will be harder to maintain for no reason.

Actually a simple and understandable code is more important than the numbers of line. Number of lines is actually not that important.

Please, let's focus on more important things like: having simple, realistic and understandable examples, good variable names, etc...

Would also be nice if we could see the total line number for all files in a way
