[FR] embedded scripting language and query language

### Description

I did not see mention of a embedded scripting language and query language in the [roadmap](https://github.com/AppFlowy-IO/AppFlowy/blob/main/ROADMAP.md)

Filing this bug to collect thoughts on
- embedded scripting language
- and data query language.

### Impact

Allows a user to make custom scripts and custom automated/manually triggered actions and data views within the markdown.
One does not have to make a full formal plugin, for small inline scripts.

### Additional Context
It will probably, also require exposing some sort an internal api and internal schema, so that the scripts have some resources to act on.

### Suggestion 1
As logseq is a closely related tool. It helps when productivity tools have such languages in common to reduce learning. Using the same embedded scripting language and query language as logseq will reduce the cognitive load on a user.

Logseq uses
- sci for embedded Clojure, which should be compile to various targets including native/javascript
- sci stands for 'Small Clojure Interpreter'
