/signcopy throws when not using quotes

Start in mechanics/signcopier/SignEditCommandsRegistration.java, especially extract$text at the stack-trace location, and reproduce the issue with /signcopy edit 1 first second. Check how the final parameter is parsed when it is unquoted. Done means unquoted line content no longer throws an exception and produces the expected result, or reports a proper error.

CraftBook Version

5.0.0-SNAPSHOT

Platform Version

26.1.2-60-main@b4682bf

Expected Behavior

In the worst case, print a proper error - but to be frank, I'd rather have the plugin simply collect the arguments without requiring enclosing quotes, as it is obvious that that's what the player wants, based on the fact that it is the last parameter - no ambiguity there. In general, having to use said quotes is a big confusion to many of our players.

Reproduction Steps

1. Copy a sign
2. Run /signcopy edit 1 first second
