package.json: remove 'init' debug attribute

We use dlv in headless mode and dlv headless server always ignores --init flag.
This seemed to be added in early days of vscode-go to support all delve flags
available back then, and it never worked.

 logOutput  | Comma-separated list of Delve components (`debugger`, `gdbwire`, `lldbout`, `debuglineerr`, `rpc`) that should produce debug output when `showLog` is `true`. This corresponds to `dlv`'s `--log-output` flag.
 logDest    | Absolute path to the delve log output file. This corresponds to `dlv`'s `--log-dest` flag, but number (used for file descriptor) is disallowed. Supported only in dlv-dap mode on Linux and Mac.
 buildFlags | Build flags to pass to the Go compiler. This corresponds to `dlv`'s `--build-flags` flag.
-dlvFlags   | Extra flags passed to `dlv`. See `dlv help` for the full list of supported flags. This is useful when users need to pass less commonly used or new flags such as `--only-same-user`, `--check-go-version`. Note that some flags such as `--log-output`, `--log`, `--log-dest`, `--init`, `--api-version` already have corresponding properties in the debug configuration, and flags such as `--listen` and `--headless` are used internally. If they are specified in `dlvFlags`, they may be ignored or cause an error.

 remotePath | If remote debugging (`mode`: `remote`), this should be the absolute path to the package being debugged on the remote machine. See the section on [Remote Debugging](#remote-debugging) for further details. [golang/vscode-go#45](https://github.com/golang/vscode-go/issues/45) is also relevant. Becomes the first mapping in substitutePath.
 substitutePath | An array of mappings from an absolute local path to an absolute remote path that is used by the debuggee. The debug adapter will replace the local path with the remote path in all of the calls. The mappings are applied in order, and the first matching mapping is used. This can be used to map files that have moved since the program was built, different remote paths, and symlinked files or directories. This is intended to be equivalent to the [substitute-path](https://github.com/go-delve/delve/tree/master/Documentation/cli#config) configuration, and will eventually configure substitute-path in Delve directly.
 cwd | The working directory to be used in running the program. If remote debugging (`mode`: `remote`), this should be the absolute path to the working directory being debugged on the local machine. See the section on [Remote Debugging](#remote-debugging) for further details. [golang/vscode-go#45](https://github.com/golang/vscode-go/issues/45) is also relevant.
