Wrong included tax information

[liveHarshit]

Tax details from API: https://open-event-api-dev.herokuapp.com/v1/events/bb9f5cc4/tax
On frontend: https://open-event-fe.netlify.com/e/bb9f5cc4

Tax should calculate in decimal. Like 90.90+9.10

@liveHarshit That was because we used an integer for ticket price and tax before, I will fix it

@kushthedude if you are busy somewhere, I would like to take this up

This can be fixed once fossasia/open-event-server#6366 is merged
