Reference search shows matches in the same file under different paths

[egamma]

• open https://github.dev/python/cpython/pull/29581
• open Include/internal/pycore_ast.h
• do a reference search for the enum FunctionDef_kind

-> the same match is reported twice in different files, but there is only a single pycore_ash.t in this repository

Looks like there is two variants of this file: one is the actual file (vscode-vfs-scheme) and another one seems to be from the review-scheme. I assume the later is from GHPR extension and should be filtered

There is a list that contains schemes that we ignore. This has debt written all over it but will do for now.

Instead of having the static filter-list we should probably have an allow list which is all schemas file-search found - plus some special scheme, like notebooks
