Show information from @active in the website

[cortinico]

Fixes #3568

The information from the @active KDoc annotation can be easily added to the website to make easier for our user to understand if a rule is active or not.

I've also cleaned up a bit the @since annotation as it was not really used.

Should we make it more clear that this is a default value? I mean, that this rule is active by default.

[cortinico]

How about the label it as "Active by default"?

[BraisGabin]

Add it just for the ones that are active by default? I like it

[cortinico]

I've added it for both actually. I think it's better to be explicit rather than implicit, or is there a reason why we want to hide it for disabled rules?

[cortinico]

Going to merge this as it is, and we can still re-discuss this if needed.
