debugger::Start ignores "save" property of task

[zjin123]

Reproduction steps

1. Change main.cpp but do not save
2. Ctrl+Shift+P
3. Select ''debugger: start"
4. Select "Debug"

$ tree -a
.
├── main.cpp
└── .zed
    ├── debug.json
    └── tasks.json

$ cat main.cpp
int main() { return 0; }

$ cat .zed/tasks.json
[
  {
    "label": "Build",
    "command": "g++ $ZED_WORKTREE_ROOT/main.cpp -o a.out",
    "use_new_terminal": true,
    "save": "all",
  },
]

$ cat .zed/debug.json 
[
  {
    "label": "Debug",
    "adapter": "GDB",
    "program": "$ZED_WORKTREE_ROOT/a.out",
    "request": "launch",
    "build": "Build",
  },
]

Current vs. Expected behavior

Current behavior:
Zed does not save the modified main.cpp (ignoring that the "save" property of the Build task) but runs the Build task and starts debugging.

(However, if Ctrl+Shift+P and select "task: spawn" the Build task, main.cpp is saved as expected before build.)

Expected behavior:
Zed saves the modified main.cpp, runs the Build task and starts debugging.
