Autocomplete : Special character rendering for Product Attribute

[PierreLeMaguer]

Preconditions

Magento Version : 2.1.12

ElasticSuite Version : 2.3.11

Environment : Developer and Production

Steps to reproduce

1. Create a product attribute and display it on autocomplete search.

Expected result

1. The value is decoded and we have a correct rendering of special characters like '&'.

Actual result

1. The value is not decoded and we can't show &. We actually show &

This problem looks like #179 but the merged request does not correct the problem for product attributes. Maybe it is deliberate ?
If not, just add a html_entity_decode on vendor/smile/elasticsuite/src/module-elasticsuite-catalog/Model/Autocomplete/Product/Attribute/ItemFactory.php l51 could be sufficient.

Actually a templating issue.
Fixed by #982
