Fix declaration-block-no-duplicate-properties reported ranges and refactor to use fix callback instead of context.fix

[Mouvedia]

Which issue, if any, is this issue related to?

#2643

Is there anything in the PR that needs further explanation?

Previously the rule always reported the last duplicate which wasn't the one being removed—if fixed—in the majority of cases.
An example of a case in which the rule did report correctly the duplicate that would be removed, was if the duplicate that remained was !important and placed before the last duplicate.
i.e. demo

Now it always reports the duplicate that will be removed.
It also helps for the diff between the range of the warning and the range returned by fix.

@ybiquitous previously I could re-run individual tests that failed due to cacheStrategy is "metadata".
Now the retry button is missing from the interface, did something change with the action?

@Mouvedia Sorry for the inconvenience. We (owners) are reconsidering and assessing the Contributors team's permissions for several reasons. I just granted you permission to write since you have been so active recently. Please let me know if you are still having any trouble. 🙏🏼

We (owners) are reconsidering and assessing the Contributors team's permissions for several reasons.

Is one of the reason the fallout of the xz backdoor? Did contributors had too many rights?

[ybiquitous]

Right, it's one reason.

Now it always reports the duplicate that will be removed.

Sounds good. Can you add a changelog item for this? I think it's a bug fix.

[Mouvedia]

I think it's a bug fix.

I consider it a preference or laziness on our part.

Can you add a changelog item for this?

Ill add a changeset, sure.

[ybiquitous]
