Update test suite to use fewer GitHub API calls

[choldgraf]

This updates our test suite to use smaller date ranges etc in order to reduce the number of API calls involved in our tests. We keep hitting rate limits, which makes iteration quite difficult in this package! I tried to pick ranges that still returned data, but much less data in general so that we don't hit our limits. Most of the changes here are just to the regression tests as a result.

I don't think we can test this until it is merged, because our tests use pull_request_target which means we don't run them on the branch, but use main instead.

@stefanv any thoughts on this? I know you ran into this too

I presume pull_request_target was to gain access to some repository secret?

What does this deploy error even mean? I don't think I ever seen these types of comments from github actions before.

OK I'm going to merge this because we aren't testing any of our PRs against the PR itself, we're just running main each time. I also think that these weird bot notices are also because of the same thing. It'll be fixed when we merge this....so I'm just gonna go ahead and do that lol
