/structure save command is missing saveMode argument in editor mode

The bug

In editor mode, the /structure save command has different syntax. Instead of having two overloads:

• /structure save <name> <from> <to> [<includeEntities>] [<saveMode>] [<includeBlocks>]

• /structure save <name> <from> <to> [<saveMode>]

It only has one:

• /structure save <name> <from> <to> [<includeEntities>] [<includeBlocks>]

This change in syntax breaks running behavior packs or command blocks in the world that use the normal syntax.

How to reproduce

1. Launch an editor session

2. Type /structure save test ~ ~ ~ ~ ~ ~ memory

Expected behavior

It should save a structure to memory

Observed behavior

Syntax error
