Filter matching context by last modification date

On Api V4: https://api.dismoi.io/v4 it would be rather easy to add such filters, see api-platform documentation:
https://api-platform.com/docs/core/filters/#search-filter

But first we must add 2 properties on the `MatchingContext` entity. Take example on the `Notice` entity:
https://github.com/dis-moi/backend/blob/master/src/Entity/Notice.php#L257-L282

Then some logic must be aded to update both dates, again you may take example on the `NoticeListener`, see the listener and the required annotation :
https://github.com/dis-moi/backend/blob/master/src/Entity/Notice.php#L33

Start with the MatchingContext entity and compare it with the properties in src/Entity/Notice.php at lines 257-282. Then read the NoticeListener and its annotation, and review the API Platform search-filter documentation linked in the issue. Done means modified matching context can be filtered by its two date properties through the API v4 endpoint.
