[FIX] Added fix for new files not being detected automatically

[jaxwilko]

This PR adds a fix to ensure that all blocks are considered when use generating the cache key.

The issue was caused by BlocksDatasource::getPathsCacheKey() not producing a cache key that included all file paths as some paths were being cached by said key. The Block CmsCompoundObject was able to detect the new files that were added but was unable to report them correctly as the hash used for caching was not being updated when the available paths were changed.

To fix this, during the BlocksDatasource init, I've added a check to ensure that both registered blocks and blocks detected by the datasource are correctly considered when generating the cache key.

This should resolve any issues of files not being available when they are available (i.e. adding a new file without clearing the cache).

Really, we should only do this check when not running in production mode, if in production we should cache this list and only fetch it when it's missing (i.e. fresh deploy / cache busted)
