Added 4 translation keys in two files

[WillyKirchner]

• solving issue missing translation keys #1168
• for my usecase of the react-chart-editor i needed translation, and discovered strings which aren't keys.
• I changed keys in two lines of ColorPicker.js and one line in DataSelector.js and added the localize variable
• after that i ran the scripts to integrate the keys in the translation-key files

@dmt0 there are checks failing. Could you point me to the issues for the checks? What would it take to merge this pull request?

Hi @WillyKirchner sorry for the huge delay and thanks for your contribution! I couldn't get the CI to work on this branch, maybe because the job is super stale. I did include your changes in my #1172. Release is coming soon. I'm gonna close this for now.
