Caret icon update for toggling options

[tooomm]

Please describe the issue

The "arrow" icon next to the Toggle Options menu is different to how it's usually utilized.

Can be seen on https://mtgjson.com/downloads/all-sets/ for example:

• collapsed:
• opened:

Default usage would be to have the caret point to the right when folded. MTGJSON have it point up. When opened and all options are available, it correctly points down.

Describe the solution you'd like

Use caret-right icon for the folded options view: https://fontawesome.com/v5.15/icons/caret-right?style=solid
