[ide] Disable the exit dialog on JetBrains IDEs

[felladrin]

Description

This disables the following exit dialog on JetBrains IDEs, as, in Gitpod, the IDE state is totally controlled by the Supervisor. So when user clicks "X" to close the Thin Client window, this dialog will not be displayed anymore.

Resolves #8037

How to test

1. Open a new workspace on any JetBrains IDE. Here are some suggestions (you just need to check one of them):
   • IntelliJ workspace on Preview Environment
   • Goland workspace on Preview Environment
   • Pycharm workspace on Preview Environment
   • PhpStorm workspace on Preview Environment
2. After the JetBrains Client is open, on the Terminal, run cat $(find /ide-desktop/backend/bin/ -name "*64.vmoptions") and confirm if the file contains the line -Dgtw.disable.exit.dialog=true (this line is appended to the file during the image build, so it should be around the end of the file).
   
3. Close the IDE by clicking "X" or by the menu option "Quit JetBrains Client").
4. Confirm that the IDE gets closed without displaying the exit dialog.

Release Notes

JetBrains IDEs won't show an exit dialog anymore, as the text on it was not necessary when running on Gitpod.

I think Werft is having the common error "no space left on device" :(

Not works for me

/hold

I've just noticed we'll need to add a .vmoptions for each JetBrains IDE (e.g. idea64.vmoptions, goland64.vmoptions, ...).

/unhold

Alright, now it works for any JetBrains IDE!
