Currently, when overriding e.g a `binary` in dap settings, one have to
override all settings, including `args` as it otherwise set it to empty
string.

E.g this config will set `args` and `env` to their empty states, like
empty string and empty map:
```json
{
  "dap": {
    "Delve": {
      "binary": "/path/to/binary"
    }
  }
}
```

This PR changes so that it is instead possible to only override a single
field. This is useful e.g on nixos where you don't want (or cant let)
zed download binaries for you, but you want to use the default args,
such as in Delve, you want zed to configure it with a random listening
port.

Release Notes:

- Improved dap settings so that it is possible to override individual
fields, such as `binary`
