Add justinvelluppillai and remove flamisz to stale issue/PR notification
Maybe later we can create a stale notifications team to make this easier but updating individuals for now
Wouldn't it be easier to just ping a team like in
<a class='mention' href='https://github.com/matomo'>@matomo</a>-org/core-team and then just update the people on the team as needed?
For this we would either need to change the core-team list or create a new team.
