feat: add events section

[jalaym825]

We need to create dedicated pages for each year of events for Club Gamma that allows users to view events from different years. Users should be able to select a year from a dropdown in the navbar, which will navigate them to a specific page displaying the events that took place in that year.

Requirements

• Add a Dropdown option in the navbar to select the year.
• Each year selected from the dropdown should navigate the user to a new page that shows all events done in that specific year.
• Ensure each events page is responsive and mobile-friendly.
• Include an easy way to update event information by fetching data dynamically from a events.json file.
• The design should be consistent with the rest of the site, using the same color scheme, fonts, and layout patterns.

Additional Notes

• Fetch the events.json data by sending a GET request to https://raw.githubusercontent.com/clubgamma/club-gamma-frontend/refs/heads/main/JSON/events.json to dynamically load event information for the selected year.
• For each year, send a request to https://raw.githubusercontent.com/clubgamma/club-gamma-frontend/refs/heads/main/JSON/markdowns/{filename} to get the relevant markdown content.
• Ensure the layout for each events page works well on both desktop and mobile devices.

Acceptance Criteria

• A Dropdown in the navbar allows users to select a year.
• After selecting a year, the user is navigated to a new page showing events from that year.
• Each yearly events page is responsive and consistent with the current website design.
• Event data is fetched dynamically from the events.json file via GitHub's API.
