[DOCS] Use of configuration option priority

[SvenJuergens]

Bug Report

a misleading description for the use of 'priority' in the TypoScript section of the documentation 'Usage'.

priority should be options.priority
like in the Tests

Prerequisites

• Can you reproduce the problem on TYPO3 v9.5 LTS
• Can you reproduce the problem on TYPO3 v10.4 LTS
• Did you perform a cursory search to see if your bug or feature is already reported?

Description

the script is not added in the head

Steps to Reproduce

1. [First Step]
   Install extension

2. [Second Step]
   Read Documentation and add example Code

plugin.tx_usercentrics {
    jsFiles {
        10 {
            dataServiceProcessor = Google Analytics
            file = https://www.google-analytics.com/analytics.js
            attributes {
                async = async
            }
        }
    }

    jsInline {
        10 {
            dataServiceProcessor = Google Analytics
            value (
             ....
            )
        }
    }
}

3. add the option priority, as seen in the documentation, at the same level as dataServiceProcessor

Expected behavior:
Script should rendered in head

Actual behavior:
Script is rendered at bottom
