FastHttpSession requests typing for the json argument should support lists

[MarcSalvat]

Prerequisites

• I am using the latest version of Locust
• I am reporting a bug, not asking a question

Description

Typing for FastHttpSession was added here but the json argument should also allow for lists, not only dictionaries.

Example:
POST /books/bulk
[
{
"title": "The Hitchhiker's Guide to the Galaxy",
"author": "Douglas Adams",
"isbn": "9780345391803",
"genre": "Science Fiction",
"publication_year": 1979,
"description": "A hilarious and thought-provoking adventure through space and time."
},
{
"title": "Pride and Prejudice",
"author": "Jane Austen",
"isbn": "9780141439518",
"genre": "Classic Literature",
"publication_year": 1813,
"description": "A witty exploration of love, class, and social expectations in Regency England."
}
]

Current implementation will show an error with mypy:

error: Argument "json" to "put" of "FastHttpSession" has incompatible type "list[dict[str, object]]"; expected "dict[Any, Any] | None" [arg-type]
