feat: add raw algolia response to access facets and fix index batch

[shanholmes]

• Add the raw response from Algolia to the output to allow access to other features from the search results such as facet counts

Added another commit to revise the indexBatch function in src/Tasks/AlgoliaReindex.php.
We were seeing that our Reindex task was failing to actually push through any records to Algolia.
This turned out to be because the call to getIndexByName only ever returns one Index, making the subsequent foreach in the try statement fail as $indexes was not iterable. Not sure why this is an issue now and my fix may not be correct but up for finding a solution regardless.
