effect the snippets for .gitignore

[WXZhao7]

I find this extension will cancel the custom snippets in .gitignore.
I create snippets in ~/.config/Code/User/snippets/gitignore.json. example:

	"test":{
		"prefix": "aha",
		"body": "vs-shell-format"
	}

This is my setting.json

    "editor.tabCompletion": "on",
    "editor.snippetSuggestions": "top",
    "shellformat.effectLanguages": [
        "shellscript",
    ],

Although I set the effectLanguages, the snippets can't work until vs-shell-format is disabled.

The language support for .gitignore is provided by gitignore.
