VSCode tasks not generating

[ilmai]

Since the update earlier today, none of the cargo tasks in my VSCode tasks.json files are being recognized. Tasks log in VSCode is full of errors like this:

Error: The cargo task detection didn't contribute a task for the following configuration:
{
    "label": "rust: cargo build debug",
    "type": "cargo",
    "command": "build",
    "problemMatcher": [
        "$rustc"
    ],
    "group": "build"
}
The task will be ignored.

The same thing happens on two different computers in all of the projects I tested. The issue is resolved by downgrading to the previous version (0.3.1885).

rust-analyzer version: 0.3.1896

rustc version: 1.77.0

I am not positive, but this running this in the debugger it looks like it might be due to 4422a90. In particular, in buildRustTask, definition.program is undefined.

still reproduces in rust-analyzer version: v0.4.1897 (pre-release) fwiw
