fix(model_deprecation): drop env-var overrides to satisfy docs validation

Browse source 
The proxy documentation lives in BerriAI/litellm-docs and any new env
key flagged by os.getenv() must be added there before the
test_env_keys.py CI check passes. Rather than fork the docs repo for
two niche tunables, hard-code the defaults:

- DEFAULT_DEPRECATION_WARN_DAYS = 30 (already overridable per-request
  via ?warn_within_days=N on /model/deprecations).
- DEFAULT_DEPRECATION_CHECK_INTERVAL_SECONDS = 24h.

Both can still be raised as env-var follow-ups together with their docs
update if operators ask for it.
