fix(ci): platforms input

[adrien-f]

Hello!

As far as I can tell, the expected input is platforms instead of platform. This give the following warning for example:

In https://github.com/BerriAI/litellm/actions/runs/7946778613/job/21694888088:

Warning: Unexpected input(s) 'platform', valid inputs are ['add-hosts', 'allow', 'attests', 'build-args', 'build-contexts', 'builder', 'cache-from', 'cache-to', 'cgroup-parent', 'context', 'file', 'labels', 'load', 'network', 'no-cache', 'no-cache-filters', 'outputs', 'platforms', 'provenance', 'pull', 'push', 'sbom', 'secrets', 'secret-files', 'shm-size', 'ssh', 'tags', 'target', 'ulimit', 'github-token']

This should restore multi platform images 👍

Can we get your help debugging ?
