Add requeue button to Ranked victory/defeat modal (#3121)

## Description:

Adds a "Play Again" requeue button to the victory/defeat modal for
Ranked 1v1 games. When clicked, it navigates the player back to the
homepage and automatically opens the matchmaking modal to queue for
another ranked match.

Changes:

- WinModal.ts: Added isRankedGame state, purple "Play Again" button
(only shown for ranked 1v1), and _handleRequeue() method
- Main.ts: Added ?requeue URL parameter handling to trigger matchmaking
modal on page load
- en.json: Added "requeue": "Play Again" translation string
- added tests to WinModal.test.ts

Note: temporarily set isRanked flag to true to get the modal to pop in a
solo match on dev server and confirmed that ?requeue URL parameter
called _handleRequeue() correctly, which opened the sign in process
since actually signing in and queuing for a ranked match isn't possible
on dev server.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
