Remove editor splash screen with sponsors logo

The Godot Project Leadership Committe has decided to update the sponsoring
tiers so that the Platinum Sponsorship no longer includes a logo on the
editor splash screen.

This lets us reclaim the editor splash screen space for community-related
content instead of sponsors (e.g. a different community-designed splash
screen for each stable branch?).

Also removes two Platinum Sponsors whose sponsorship has expired earlier this
year.

(cherry picked from commit c283fce698)
