Github Actions uses invalid environment variables.

I'm trying to test this action locally before creating my own. However the action only echo's hello. When I try to set the environment variable:

export INPUT_WHO-TO-GREET=test
bash: export: `INPUT_WHO-TO-GREET=test': not a valid identifier

It fails? It seems Github Actions allows - in its Environment variables but bash doesn't.

export INPUT_WHO-TO-GREET=test bash: export: `INPUT_WHO-TO-GREET=test': not a valid identifier

xport INPUT_WHO-TO-GREET=test bash: export: `INPUT_WHO-TO-GREET=test': not a valid identifier

When testing this locally, it looks like @actions/core library is looking for the INPUT_WHO_TO_GREET environment variable instead. Hyphens are being replaced with underscores. Let me know if that helps!
