fix: remove download size badges

[wesleytodd]

I missed that this was added in #5619 and would have opposed it if I had noticed. These badges are misleading in too many cases to make it worth including. Having seen some of the most wild projects and the impact of install time, I can confidently say that publishing more versions (aka the packument gets larger) is much worse of a problem than all but the most absurd cases of tarball size.

Anyway, it came up here so I thought I would open this PR to discuss.

I agree with you here, but I think this should even be a bit more drastic - we should have another readme used in the package.json
there is other assets that could be removed but I think we can have a side discussion about that

I am neutral to this change 👍
