Fix for Latin Names

[gustavocs97]

Problem:

• Names coming from sources like OpenFoodFacts may contain HTML entities (e.g. é, ú).
• As a result, the name parameter in the Grocy URL becomes:
  Bebida%20energ%26eacute%3Btica%20..., and Grocy receives é instead of é.

Fix:

• Replace htmlspecialchars_decode with html_entity_decode and specify UTF-8:

Line: 395

SOLUTION

- rawurlencode(htmlspecialchars_decode($item['name'], ENT_QUOTES))
+ rawurlencode(html_entity_decode($item['name'], ENT_QUOTES, 'UTF-8'))
