Fix search packet and entity change action extra data

[DrexHD]

Check discord for details.
TLDR:

• Search packet was incorrectly updated during the 1.20.5 update.
• The entity change action extra data field only stores the item id of items that are used during item changing. This is inconsistent with other actions and causes hovering over the action message to not show item details such as enchants. This has been fixed by storing all item data and if item data can't be parsed falling back to the old format (for de-serialization).
