fix: update help and support link

[sandrade-dcl]

What does this PR change?

The Decentraland's support page has changed from the url https://intercom.decentraland.org to https://decentraland.org/help. So we have changed it for the corresponding buttons in the Explorer:

• Taskbar "?" button.
• Explore menu -> Settings -> CONTACT SUPPORT button.

How to test the changes?

1. Launch the explorer
2. Click on the "?" button in the taskbar and observe the new url is open.
3. Go to Explore menu -> Settings -> CONTACT SUPPORT button and observe the new url is open.
