Add strings announcement for Milestone Reward for reset system

Hi devs,

I would like to suggest adding a personalized announcement to the screen, allowing you to define colors and how the awards that the reset system allows us to deliver to Players after reaching the reset milestones required by the settings will be announced.

Something similar to this, I am testing a (private) server for season 20 and I found this extremely cool.

After reset my character I receive some rewards then, the system reset send-me this information.

That cools !
