fix: use bearer auth instead of token

[frco9]

On a GHES instance, I had the following error when using the action :

Error: Error checking PR comments: Bad credentials - https://docs.github.com/rest

I've tried to also pass a PAT, and error was the same.

As per Github documentation it seems for most cases we should use Bearer instead of token for auth param.

With this fix I don't have auth error anymore.

Thanks @frco9 - Let me test a couple things here to make sure this works.

Looks good. Let's just remove the /dist updates here (as the workflow does that automatically)

Thanks for review @virgofx. I've updated the PR.

Thanks @frco9 - I'm going to test one more thing then cut a release (hopefully Monday/Tuesday)

hi @frco9 - I have a pre-release out v1.7.0 that contains the fix here. If you're able to explicitly reference this version, test, and confirm working, that would be great! Thanks
