Git on Windows: fatal when adding or removing files due to drive lowercase letter

[asn007]

• VSCode Version: 1.50.0
• OS Version: Windows 10
• Git version: 2.19.2.windows.1

Steps to Reproduce:

1. Open VSCode on Windows
2. Create a new project
3. Try to add new files to the index via SCM GUI

Expected result:
Files are added/removed to index successfully

Actual result:
Error message: `fatal: d:[filepath] 'd:[filepath]' is outside repository

Extension console output:

It seems that the VSCode Git extension does not call sanitizePath() inside git.ts on filenames while adding/removing files.
It does, however, with invocations like ls-remote, which is seen from the output message

Does this issue occur when all extensions are disabled?: Does not apply, extension issue

Seems that #88272 (comment) also has the same issue

After a brief search, I've realized that the issue also exists in clean method. I've filed a PR to fix the issue: #108691
