Anvil character limit is too low for items with long names

Bedrock equivalent of MC-203757

The name for the Lingering Potion of the Turtle Master is too long to rename in an anvil.
Java's solution is to lengthen the anvil character limit to 50. (note that this was previously 35 on Java while on Bedrock it is currently 30)

Steps to reproduce

1. Attempt to rename a Lingering Potion of the Turtle Master in an anvil
   →  You can remove the text " Master" but not type it back
