Configuration: Invalid neovimPath. Using neovim installed via snap

Describe the bug

I've neovim installed via Snap(https://github.com/neovim/neovim/wiki/Installing-Neovim#snap):

➜ /snap/bin/nvim --version
NVIM v0.5.0-nightly-6-gef0398f
Build type: Release

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/usr/share/nvim"

Run :checkhealth for more info

After setting:

"vim.neovimPath": "/snap/bin/nvim", it gives me the error:

Configuration: Invalid neovimPath. Command failed: /snap/bin/nvim --version need to run as root or suid .

But as you could see above, there is no root needed to run /snap/bin/nvim --version.
Also I can reproduce #4902 where I get:

Configuration: Invalid neovimPath. The argument 'file' cannot be empty. Received ''.

To Reproduce

Install nvim via snap:

1. sudo snap install --beta nvim --classic
2. Set "vim.neovimPath": "/snap/bin/nvim", in thesettings.json with neovim enabled

Expected behavior

No error message.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.14.5
• VSCode version: 1.45.1
• OS: Ubuntu 18.04.4 LTS

Start by tracing validation of the vim.neovimPath setting and the command execution used for /snap/bin/nvim, then reproduce the issue with the snap installation and settings.json configuration described. Done means the extension accepts this path and reports no invalid-configuration error while retaining the existing behavior for other Neovim paths.
