Fix: MetaMask links

[hmalik88]

Description

Write a short description of the changes included in this pull request, also include relevant motivation and context. Have in mind the following questions:

1. What is the reason for the change? MetaMask links are broken in Snap dialogs.
2. What is the improvement/solution? Since it's not possible to programmatically open the extension, it isn't possible to navigate from a Snap dialog to a MetaMask route (home screen or Snap page). The proposed solution is to cancel the dialog and just open the MetaMask link in a new tab if we're in a "notification" environment.

Related issues

Fixes: #29978

Manual testing steps

1. Build the extension with this branch
2. Trigger a snap dialog with a MetaMask link
3. Visit the link and observe that it opens in a new tab.
