Following D9244, update KateConsole::slotSync (the directory synchronization in terminal)
to use KTextEditor::Message as an information, when the file is not local.
Previously, a string starting with `### ` was output to the terminal.
This might have been annoying if the '#' character was not a comment
for the interpreter currently running in the terminal.
The chosen level is just "Information", because when
"Automatic synchronize" is on,
the expected behavior is just a no-op.
