docs(virtual_keys): document allowed_routes in default_key_generate_params

[devin-ai-integration]

Summary

Documents the new allowed_routes support in litellm_settings.default_key_generate_params (BerriAI/litellm branch litellm_default_key_generate_params_allowed_routes, Linear LIT-7788). Adds the field to the yaml example in docs/proxy/virtual_keys.md and a sentence explaining that it fills unset requests, that a non-empty value is an allowlist (so llm_api_routes must be included alongside /key/spend/report), and that a key_type preset on the request takes precedence

Low Risk
Documentation-only; no runtime or config parsing behavior changes in this diff.

Overview
Updates docs/proxy/virtual_keys.md so litellm_settings.default_key_generate_params documents allowed_routes: defaults apply when the field is missing or null (like other params, with the same budget_duration exception noted elsewhere). The new text explains using ["llm_api_routes", "/key/spend/report"] so new keys can report spend, that a non-empty value is an allowlist (so route groups such as llm_api_routes must be included), and that an explicit key_type on the request wins over the default.

The sample default_key_generate_params YAML now includes allowed_routes. A stray blank line under the Teams API reference heading is removed.
