Mcdoc files in mcdoc subdir are prefixed with ::mcdoc after closing and re-opening vscode

[NeunEinser]

Steps to reproduce

1. Open vscode in an empty directory
2. Create a sub directory called mcdoc
3. Create a test.mcdoc file inside of it
4. Create a struct definition called Test
5. Hover over its definition
   -> ✅ The struct's full path shows up as ::test::Test
6. Close vscode
7. Open vscode
   -> ✖️ The struct's full path shows up as ::mcdoc::test::Test

Notably clearing the cache does not fix this issue, not even temporarily.

What I expected

The definition should be consistently ::test::Test

What happened

After reloading vscode, the definition becomes ::mcdoc::test::Test
