Enhance get tickets button design

It closes #324
I increased the padding-bottom of the hero image, so that the text stays more on top of the Eiffel Tower.
I also added a shadow behind the button so it stands out more.

👍🏽 to increasing the size of the button
👍🏽 adding a shadow to give more importance to the button

I still see some opportunities to improve the importance of this button a little bit:

Improve the contrast ratio

The contrast ratio can reach better numbers. I found an interesting website where we can play with the colours of the background and the button to achieve a better contrast score:

The values I introduced:

--surface: #8a83c7;
--background: #2a3b90;
--color: #f9ead4;

Social Buttons still are bigger

When checking the page, the Social Buttons still are bigger. Some ideas we can experiment with are:

• 💁🏽💡 Increase the font-size for the GET YOUR TICKET button
• 💁🏽💡 Increase the area (padding) for the GET YOUR TICKET button
• 💁🏽💡 Decrease the area (padding) for the Twitter and Mailing List buttons.
• 💁🏽💡 Make the icons appear in the same line with the text to make the button smaller.

Actually, we can merge what you did and we (I can do it) can do another iteration in a different PR.

Seems good to me, I will merge it and I can take a look again on this tomorrow

Thank you, that's an improvement, the box shadow really lifts it out. It still blends in with the Eiffel Tower behind it – if could dim the background somehow, I think that would solve it but there might be other ways to achieve the same.

I created a new issue where we can keep iterating the button: #363
