gopls/doc: remove unnecessary settings from VSCode documentation

The EOL setting is no longer needed, as the issue it was correcting
has been fixed. The file watching setting is not really being respected
correctly in the current version of gopls, as we are currently reworking
it.

 VSCode will complain about the `"gopls"` settings, but they will still work. Once we have a consistent set of settings, we will make the changes in the VSCode plugin necessary to remove the errors.
