[Bug] `search.exclude` is not working for `workbench.action.showAllSymbols`

[wenfangdu]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: v1.59.1
• OS Version: Windows 10

Steps to Reproduce:

1. Make sure node_modules is excluded from search.exclude.
2. Use workbench.action.showAllSymbols.
3. Type in a symbol name that exists in node_modules.
4. That symbol shows up in the search result.
