188cc932 - move `REPL.REPLCompletions.UndefVarError_hint` to `REPL` module (#52990)

move `REPL.REPLCompletions.UndefVarError_hint` to `REPL` module (#52990) Since `UndefVarError_hint` is an interactive feature and isn't directly related to completion, it seems more appropriate to place it within `REPL` module rather than its `REPLCompletions` submodule.
