fix: remove claude-3.7-sonnet from VS Code LM blacklist to show in model dropdown

Fixes #6292 - Claude 3.7 Sonnet was being filtered out from the VS Code Language Model API provider list due to being in the static blacklist. This change removes it from the blacklist so it will appear in the dropdown when available through the VS Code LM API.
