explorer.excludeGitIgnore stops at the first .gitgnore file it finds instead of walking up the tree to the git repo root

Type: Bug

Repro recipe:

mkdir vscode-gitignore && cd vscode-gitignore && git init && echo 'test-directory/' > .gitignore && mkdir .vscode && echo '{ "explorer.excludeGitIgnore": true }' > .vscode/settings.json && mkdir -p subdir/test-directory && touch subdir/.gitignore && cd subdir && git status &&  /Applications/Visual\ Studio\ Code.app/Contents/MacOS/Electron --disable-extensions .

Expected: test-directory is hidden from file explorer since it's missing from the git status output.

Observed: test-directory is present in the file explorer.

I believe this is happening because VSCode is finding & using subdir/.gitignore without consideration of the top-level .gitignore file in the parent directory. Since git ignore considers all .gitignore files in the repo between the destination and the root, IWBN for excludeGitIgnore to do the same.

(the practical effect of this is having to duplicate entries from the root .gitignore file into descendant .gitignore files to get VSCode to ignore them)
