tsh ssh -Y doesn't work for server jumps

[Joerger]

Expected behavior:

x11 forwarding should work as you jump from server to server.

> tsh ssh -Y server01
(server01) > xeyes 
(server01) > tsh ssh -Y server02
(server02) > xeyes 

Current behavior:

x11 forwarding fails on server jump

(server02] > xeyes
Error: Can't open display: :10.0

Workaround:

This works as expected with ssh, including for Teleport nodes, so the issue likely lies with tsh. Since ssh doesn't support per-session MFA, this isn't always a valid workaround.

Bug details:

• Teleport version: v16.4.0, likely all existing versions
