Bug Description:

When an integrated terminal is opened, it does not load, and backend freezes. Sometime later, backend repairs but not the terminal

Steps to Reproduce:

1. Open a terminal in Theia IDE AppImage
2. Terminal does not load
3. Instead, theia backend goes offline.

• Operating System: Kubuntu 24.10, Plasma 6.1, 8GB Ram, 4GB Swapfile swappiness=60(default)

I saw this also already happening on 1.49.0. I'll see if i can take a look in the nex days

@DevelSSN Could this be related to this issue microsoft/node-pty#578?
would it be possible for you to check your nofile limit?

@DevelSSN This problem seemed to be related to the node-pty spawn helper, which they removed in 1.0.0. I create a PR to upgrade node-pty here. If you like you can test if that fixes your issue

I have tested this pr on top of theia 1.55.0, works fine. Thanks a lot.
