Bug: go_(next/prev)_heading jumps to lines starting with `#` in code blocks

[mmirus]

When using the default ]] and [[ mappings to jump to the next or previous heading, lines in code blocks that start with # are also jumped to.

Given the example below, if the cursor started on the first line and I pressed ]] three times, I would jump to heading one, to the comment in the shell code block, then to heading 2.

# Heading 1

```sh
# This is some example command:
some_example --command
```

# Heading 2
Yada yada...
