Change comma delimiter to triple pipe

[MattDeWeerd]

This pull request updates how shop location data is serialized and deserialized in the FoundShopsMenu class to improve parsing reliability. The delimiter used to separate location data fields has been changed from a comma to a unique string sequence.

Location Data Serialization and Parsing:

• Changed the delimiter for shop location data from a comma (,) to a triple pipe (|||) in both serialization (setLocationData) and deserialization (handleShopItemClick). This reduces the risk of parsing errors if any field contains a comma.
• Player Warp names can contain , and some shops use Stone,Wood,More! as their shop name.
• Technically a shop name can contain |||, but it is less likely
