Fix json_set() value argument type

[nafraf]

Current behavior:
json_set fails trying to set a numeric value:

Example:
In Redis server, create a new json document user:100 with two fields: name, age add random values to them.

GitHub Copilot

Ran json_set - my-mcp-redis-server (MCP Server)

Input

{
  "name": "user:100",
  "path": "$",
  "value": "{\"name\": \"Alice\", \"age\": 27}"
}

Output

Error executing tool json_set: 1 validation error for json_setArguments
value
  Input should be a valid string [type=string_type, input_value={'name': 'Alice', 'age': 27}, input_type=dict]
    For further information visit https://errors.pydantic.dev/2.10/v/string_type

Change:
The type of json_set value argument is changed to JsonType.
The definition of JsonType is the same used by redis-py

Thanks a lot @nafraf. Maybe we can also use it directly

from redis.commands.json._util import JsonType

Without redefining it. What do you think?

@mortensi You are right! Thanks.
