Update repositories.json

Whitelist is in a place acting as a first defence against malicious people that want to misuse Flux in order to for example mine cryptocurrencies or distribute illegal or copyrighted material.
To whitelist an application for Flux, please adjust helpers/repositories.json file by adding your desired whitelist for a specific docker image organisation (recommended), docker image or target a specific tag of an image:
Valid Examples: runonflux, runonflux/website, runonflux/website:latest, public.ecr.aws/docker/library/hello-world:linux, ghcr.io/handshake-org/hsd
What do you want to Run On Flux?
i want to run a java 1.8 Minecraft server. A minecraft server is a server for the popular game called "Minecraft" with over 500 million copies sold, its no dought that someone has prolly already ran a minecraft server in flux. My server will be one for me and my friends.

Is your desired application running somewhere already?
No

Is your application open source?
No
Checklist:
 ✔️Whitelist of application is only modifying repositories.json file
 ✔️repositories.json is still a valid JSON file
 ✔️Only whitelists single docker image organisation (one whitelist at a time, more whitelists, more PRs)
 ✔️No other whitelist has been deleted
 ✔️I agree with ToS https://cdn.runonflux.io/Flux_Terms_of_Service.pdf
 ✔️Application follows ToS - Application is not malicious. Application is not a scam. ✔️Application does what is meant to do and does not mislead in any way. Application does not do ✔️anything illegal. Application is not a mining application (not even bandwidth mining).
 ✔️In case application receives multiple reports, behaves maliciously, it will be blacklisted and removed from the network.
