Use Markdown codeblocks for Logseq's custom syntax

In Logseq we have custom syntax that doesn’t look nice in other tools, for example:

{{query #quotes}}

will be parsed as a normal line and tagged with #quotes in Obsidian.

I just discovered how in Obsidian they solved this: they usually introduce new syntax using standard Markdown codeblocks, so for example their query

```dataview
something
```

will be rendered as codeblock in tools that don’t support it like Logseq.

I think Logseq should switch to this approach too:

```lq-query
#quotes
```

that should be enough to inform other tools not to parse it for tags and other things.
