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.nightscout

• [E016] No SPDX license found in package.json. Please use one of listed here: https://spdx.org/licenses/
• [E116] No SPDX license found. Please use one of listed here: https://spdx.org/licenses/
• [E154] common.dependencies must contain [{"js-controller": ">=2.0.0"}] or later - recommended: [{"js-controller": ">=5.0.11"}]
• [E605] No actual year found in copyright. Please add "Copyright (c) 2023 bluefox dogafox@gmail.com" at the end of README.md

I have also found warnings that may be fixed if possible.

• [W171] "common.title" is deprecated in io-package.json
• [W105] "common.titleLang" should be translated into all supported languages (en, de, ru, pt, nl, fr, it, es, pl, uk, zh-cn)

Thanks,
your automatic adapter checker.
