Suggestion: Native WSL support for open links

[jtrungle]

Hi, first of all thanks for creating this plugin!

Since wsl utilities is being archived, figured it might be good to change Open action to use powershell command instead

#/lua/gitlinker/actions.lua L:18
  elseif vim.fn.executable("powershell.exe") > 0 then
    vim.fn.jobstart({ "powershell.exe", "-Command", "Start-Process", url })

It looks good, would you create a PR for this?
And for "wslview" and "powershell.exe", which one should have higher priority?
