tmux: prevent WezTerm version injection on attach

WezTerm would inject this version string into tmux as human-typed input:

  0;10;1c>|WezTerm 20220408-101518-b908e2dd

This would trigger my Alt+Shift+P shortcut in tmux, prompting for input.
Pressing anything other than escape at this point would crash tmux 3.2a.

This patch solves the problem by slowing down tmux's recognition of my
escape key presses.  See microsoft/WSL#5931
