Speedrun.com game variables don't show in the auto-submit dialogue

[glacials]

Not sure if this was always the case, but it appears speedrun.com run submissions can ask for both game variables and category variables. When we show the speedrun.com auto-submit form, we only render category variables, even though we also know about & synchronize the game variables.

This can lead to an impossible-to-autosubmit run if a game variable is set to required by the game's mods.

To reproduce (safely, without risking submitting a test run to speedrun.com):

1. Go to https://www.speedrun.com/world_war_z#Episode_1_New_York_DLC
2. Click Submit run
3. See that the variables asked for are Players, Difficulty, Version, and Platform
4. Go to https://splits.io/71wj
5. Export the run (I used the exchange format)
6. Upload the exported run so that you own the copy
7. Click auto-submit

Expected: we ask for all the same variables as in step 3
Actual: We only ask for Version and Platform
