Think about to fix the issues found by adapter checker

[ioBrokerChecker]

I am an automatic service that looks for possible errors in ioBroker and creates an issue for it. The link below leads directly to the test:

https://adapter-check.iobroker.in/?q=https://raw.githubusercontent.com/ioBroker/ioBroker.icons-addictive-flavour-png

• [ ] No adapter are allowed in the repo without admin3 support
• [ ] No SPDX license found. Please use one of listed here: https://spdx.org/licenses/
• [ ] Licenses in package.json and in io-package.json are different

Thanks, your automatic adapter checker.
