Subject: [PATCH] Fix attach to process in Go debugger (#43898)

Release Notes:

- Fixed the behavior of the attach to process feature for the Golang
debugger.

**Step to reprorduce:**
1. Build and run golang binary
2. In Zed open debugger
3. Go to Attach tab
4. Select the binary you just built from the list
**Actual result:**
```
Tried to launch debugger with: {
  "request": "attach",
  "mode": "debug",
  "processId": 74702,
  "stopOnEntry": false,
  "cwd": "/path/to/the/current/working/directory"
}
error: Failed to attach: invalid debug configuration - unsupported 'mode' attribute "debug"
```

**Expected result:** The debugger can attach to the process.


According to the [Delve
documentation](https://github.com/go-delve/delve/tree/master/Documentation/api/dap#launch-and-attach-configurations)
`attach` request supports `local` and `remote` values only
