Missing type annotation for FILTERS

When using Jinja2 with filters, Pylance is screaming at me because Environment.filters is partially unknown.

Environment.filters is copied from here: https://github.com/pallets/jinja/blob/5ef70112a1ff19c05324ff889dd30405b1002044/src/jinja2/filters.py#L1812

FILTERS does not have a type annotation.

You already defined a TypeVar for the expected signature here:

https://github.com/pallets/jinja/blob/5ef70112a1ff19c05324ff889dd30405b1002044/src/jinja2/filters.py#L44

Is there a specific reason to leave out the annotation? I'd be happy to submit a PR.

# Suggested code
FILTERS: dict[str, F] = {

Environment:

• Python version: 3.12
• Jinja version: 3.1.6
• I searched for other issues with the keywords type and filter
• I tested the suggested changes locally by modifying jinja in my venv
