Application whitelist

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

Please provide a POC link to application if it is already running somewhere. (optional)

[x] Whitelist of application is only modifying repositories.json file
[x] repositories.json is still a valid JSON file
[x] Only whitelists single docker image organisation (one whitelist at a time, more whitelists, more PRs)
[x] No other whitelist has been deleted
[x] I agree with ToS https://cdn.runonflux.io/Flux_Terms_of_Service.pdf
[x] 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).
[x] In case application receives multiple reports, behaves maliciously, it will be blacklisted and removed from the network.
