accept suggestion with tab and complete bracket

[GladioFeng]

Problem

In jupyter lab, the default accept suggestion keybinding is enter, can this keybind change to tab? just like vscode or pycharm behavior.

the default tab behavior is switch suggestion in jupyterlab, and I did not find a setting to change this.

Proposed Solution

Accept suggestion with tab and complete bracket
just like vscode or pycharm

• press tab key and the print() will completed

This will be possible with LSP once completer allows for snippets support, see #15026.
