Test the updated GitHub action

[gramster]

My pyright test action, which is forked from Jake Bailey's but adds the warn on partial option, just got updated with the latest changes from Jake's, which are quite extensive. It would be good to kick off a test run of the stubs (I don't have permission). If things aren't working please open an issue at https://github.com/gramster/pyright-action

I was on vacation last week. Kicked off a run now and everything looks good.

@gramster Would you like to be added as a maintainer of this project?
