Patch Changes

• #3842 2367708 Thanks @gcanti! - add support for Schema.OptionFromUndefinedOr in JSON Schema generation, closes #3839

  Before

  import { JSONSchema, Schema } from "effect"
  
  const schema = Schema.Struct({
    a: Schema.OptionFromUndefinedOr(Schema.Number)
  })
  
  console.log(JSON.stringify(JSONSchema.make(schema), null, 2))
  /*
  throws:
  Error: Missing annotation
  at path: ["a"]
  details: Generating a JSON Schema for this schema requires a "jsonSchema" annotation
  schema (UndefinedKeyword): undefined
  */

  After

  import { JSONSchema, Schema } from "effect"
  
  const schema = Schema.Struct({
    a: Schema.OptionFromUndefinedOr(Schema.Number)
  })
  
  console.log(JSON.stringify(JSONSchema.make(schema), null, 2))
  /*
  Output:
  {
    "$schema": "http://json-schema.org/draft-07/schema#",
    "type": "object",
    "required": [],
    "properties": {
      "a": {
        "type": "number"
      }
    },
    "additionalProperties": false
  }
