Specifying an initial input of org-ql-completing-read

Hello,

Would you add support for an initial input parameter to `org-ql-completing-read`? That is, I want to specify the initial input of `completing-read` called inside the function.

I use the function to find a link target in org-mode. It would be convenient if the word at point (if any) were provided as the initial input. A query prefix is unsuitable here, because I sometimes have to moderate the text.

I don't think it would be difficult to extend the API. What do you think?
