Why:

Closes actions/cache#556

What's being changed (if available, include any code snippets, screenshots, or gifs):

Cache cannot be shared between sibling branches and tags. The documentation doesn't account for tags.
Note: There is a Japanese translation as well for this document. A little unsure how that can be updated
