Description of Changes

Here is reference: #25

---

support 'custom your created block' block

• Please add the block you created to replace the 'crate' block.

• ex) add react-katex dependency to support equation block
  -> add custom solution for rendering 'your custom block'

Review point

• ex) Instead of adding the react-katex dependency, should I create a custom solution specifically for this project?
  -> Should we integrate an existing solution or use a custom implementation for 'your custom block'?

To reproduce

• npm run story:start
• click 'your created block' on the Storybook left side panel

Screenshot

• A screenshot of your created block being rendered in Storybook.

Review Guide

Reviews are conducted based on priority levels, such as p0, p1, p2, p3, p4, and p5.
p0 ~ p2: If the author decides not to reflect a review for p0 to p2, it signals that a proper discussion with the reviewer is
necessary. It is expected that the review will be resolved either through incorporating the feedback or through further discussion.
p3: indicates that the reviewer has identified a significant issue, but either lacks a clear solution or the comment lacks sufficient context. Further explanation or additional discussion on the reviewer's concerns is needed.
p4, p5: p4 and p5 suggest low priority, and if the author does not deem them important, these comments can be disregarded.
