Documentation for Surreal::import mentions .sql file

[ActuallyHappening]

See this documentation: https://docs.rs/surrealdb/latest/surrealdb/struct.Surreal.html#examples-22

The code block read:

// Select the namespace/database to use
db.use_ns("namespace").use_db("database").await?;

db.import("backup.sql").await?;

Shouldn't this be a .surql file instead? Can surreal really import from arbitrary .sql files?
