fix: Update Contribution Count Label to 'Last 365 Days' (Fixes JhaSourav07#223) (JhaSourav07#831)

This Pull Request updates the description label on the contribution
metric from `'Last Year'` to `'Last 365 Days'` to match the rolling
12-month data retrieved from the GitHub API, resolving user confusion.
