Completing % "brace" in lang-liquid

[knpwrs]

I am making an editor using the lang-liquid package. I am using the basic setup extension, as well as the liquidCompletionSource. When I type an opening brace like {, it autocompletes the closing }; however, when I type a % inside the braces, it does not autocomplete that:

Compare this to the monaco editor, where % also autocompletes:

Is there any way I can additionally autocomplete the % in CodeMirror like it does in Monaco?

This patch adds this to @codemirror/lang-liquid.

Add percent-sign closing extension

I just gave it a spin and it works beautifully, thank you!
