Generate image to display rank

[ArmandBriere]

Is your feature request related to a problem? Please describe.
The rank is the core feature of the bot right now, having a nice image to display instead of the text from the level command would be nice

Describe the solution you'd like
Generate dynamic image from the firestore data, should be done in python with PIL or using image2PDF (or something like this, the project is no longer maintained I think)

Some design template could be done before starting this feature, the work would be considered a POC if done before the design template
