Do not reprint the prompt on YDB CLI completion

[vityaman]

Currently YDB CLI reprints a prompt on completion like psql, ClickHouse CLI, what makes queries writing not so pleasant.

This is because it uses Replxx -- a C++ replacement for the GNU Readline.

An example from psql:

Fixing this is not so easy and requires patching a tricky code of Replxx, but is possible, as, for example, Python 3.13 REPL and ZSH do not reprint a prompt.
