Corrected wrong documentation! Key in javascript configuration "dataProcessingService" should be "dataServiceProcessor".

Thank you for your pull request. Can you please elaborate why you think the configuration is wrong? At least in the develop branch, dataServiceProcessor is deprecated in favor of dataProcessingService.

When people find this extension at https://extensions.typo3.org/extension/usercentrics/ and install it via composer with composer req t3g/usercentrics the latest version will be installed, in which dataProcessingService does not exist. At extensions.typo3.org you click on Extension Manual and then on Usage. The given example didn't work for me. So I had to check the Github Repository to find out that "dataProcessingService" will be used in future, but at the moment only "dataServiceProcessor" works for me.

So this PR relates to already released versions only. Thanks for clarification, I'll re-check this ASAP.

You are totally right. Maybe just adding a warning is the better way than changing the argument name.
