Checkout all history and tags in pypi workflows

[marksweb]

By default actions/checkout only fetches the most recent commit. So I don't think there were any tags to describe.

In my test I hit the unauthorised pypi error which is positive, hopefully this can now get the latest tag.

what I currently do, setting the version to the timestamp if there is no tag works, so not sure if this is needed.

@timthelion I'd hope that this means you don't hit that exception and that the tags are available to the VM.

It's also got the added bonus of bumping the actions to v3 which recently came out.

You're right, you don't need it. But it'd be nice if it released with the original style and took the tags from the github release.
