editors/zed: workaround for GDB issue

This patch is temporary workaround for GDB issue reported in GitHub:

https://github.com/zed-industries/zed/issues/41753

The subtle is incorrect handling of "setExceptionBreakpoints" resulting into
message "error: notStopped". To avoid it let's skip this call for a while.

At least it works for me
