[Eco Bounty] IoTex Outdated Copyright Year in Footer

1. Description

The footer of the official IoTeX Documentation site displays an outdated year. Even though the current year is 2026, the footer still displays "IoTeX 2025". This indicates that the global footer component has not been updated for the new calendar year.

2. Steps to Reproduce

1. Open a web browser.

2. Navigate to https://docs.iotex.io.

3. Open the sidebar navigation menu (if on mobile) or scroll to the bottom of the page.

4. Observe the text at the very bottom of the menu/footer.

3. Expected Result

The footer should reflect the current year: "© 2026 IoTeX" or simply "IoTeX 2026".

4. Actual Result (The Issue)

The footer remains static with the text "IoTeX 2025".

5. Technical Observations

• Static Value: The year is likely hardcoded in the documentation framework's configuration file (e.g., docusaurus.config.js or mkdocs.yml) rather than using a dynamic date function.

• Brand Perception: Outdated copyright years can give users the impression that the documentation or the project itself is no longer being actively maintained.
