Describe the bug

Related to #436

As was uncovered during discussion here: https://github.com/zk-org/zk-nvim/discussions/176#discussioncomment-10054556

The trigger pattern outlined here for regular markdown links is not triggering lsp completion properly.

We have previously looked at a similar issue with wikilink completion: zk-org/zk#397

How to reproduce?

1. open a note
2. type [link]((

LSP completion should trigger.

zk configuration

n/a. (although `link-format` in config will define how the link is subsequently inserted).

Environment

zk 0.14.1
system: Darwin 23.4.0 arm64

I just wanted to mention I also get this behavior. More specifically:

• Completion does not trigger when I do something like: [a link]((
• However, it does trigger when there is a space before the ](( completion pattern. So doing some text ](( triggers completion.
  • This removes the square bracket, when accepting the completion, however, leaving something like some text(path-to-file)

I cannot reproduce the issue reported in #436, however (I'm on version 0.14.1, not the main branch).

Thanks for reporting. Your tests seem to be consistent with another user here: https://github.com/zk-org/zk-nvim/discussions/176#discussioncomment-10056002
