Update MPL license to https

[Darkspirit]

Current MPL license (https://www.mozilla.org/en-US/MPL/2.0/) contains an https link:

This Source Code Form is subject to the terms of the Mozilla Public License, v. 2.0. If a copy of the MPL was not distributed with this file, You can obtain one at https://mozilla.org/MPL/2.0/.

This change would not remove the summary above the LICENSE file. Tested here.

I didn't update the tests folder with this change because I haven't yet looked into what needs to be considered with regards to WPT. Let's do that with a separate PR.

This change is splitted into multiple parts to prevent any "Load diff" button instead of a preview and was made with following commands:

git checkout -b mpl_https
