[FEAT] Add Syntax Highlighting and Validation for Elasticsearch REST DSL Requests

[yezhoujie]

Description
Can add syntax highlighting and validation when writing Elasticsearch REST DSL requests like Kibana? Without syntax highlighting and validation, users have to manually input the DSL, which is prone to errors. Additionally, the DSL syntax for Elasticsearch is quite difficult to remember.

Having syntax highlighting and validation would make it faster and easier for users to write Elasticsearch query DSLs, reducing the likelihood of errors and improving the overall user experience.

Thank you!
