Subject: [PATCH] [TASK] Add GET parameter to JS files fetched via RequireJS
As most files are loaded via RequireJS now, the configuration
needs to add a GET parameter in order to avoid browser caching
of changed JavaScript files.
For development environments the current timestamp is added. For
other environments / application contexts a hash based on the
TYPO3_version is added, allowing to have end-users to fetch
the latest version after e.g. TYPO3 has been updated.
Resolves: #68133
Releases: master
