When in bash mode (`!`) tab should autocomplete, not switch to next tab

[petrroll]

Describe the bug

When in bash mode (wrote !) tapping tab should autocomplete shell according to my shell rules, not switch to next tab. This is especially horrendous for trying to add filename as param to a shell command.

Affected version

Copilot v1.0.70-0

Steps to reproduce the behavior

1. copilot
2. !

Expected behavior

File gets autocompleted (or any other shell command does).

Additional context

• Windows / WT / pwsh.exe (but doubt that has any impact)
