Tags declared in path.yaml attach to file, but not to entire tags system

[wyattjsmith1]

Describe the bug
Creating tags in a .yaml file creates the tag on the file, but the tag is not visible in the tags page, and clicking on the tag 404s.

To Reproduce
Steps to reproduce the behavior:

1. Create a file tree like this:

some_dir/
- my_file.md
some_dir.yaml

Where some_dir.yaml has the following:

tags:
- my_tag

2. Generate and visit the my_file.md page.
3. Observe the tag my_tag exists on the page.
4. Click my_tag; observe a 404.
5. Go to the root tags page (click the 🏷️ icon at the bottom of every page)
6. Observe there is no entry for my_tag

Expected behavior

• Clicking tag should not result in 404.
• All declared tags should appear in the tags page
