jax releases html page needs HTML doctype

[hawkinsp]

pip issued the following warning to me when installing from the GCS bucket:

warning: missing-index-doctype

× The package index page being used does not have a proper HTML doctype declaration.
╰─> Problematic URL: https://storage.googleapis.com/jax-releases/jax_releases.html

note: This is an issue with the page at the URL mentioned above.
hint: You might need to reach out to the owner of that package index, to get this fixed. See https://github.com/pypa/pip/issues/10825 for context.

It seems like there's little downside to adding a doctype, so we should probably just do that.

Is this similar to the issue reported in #5410?

[hawkinsp]

I think it's related to the issue in the last comment in that issue, but maybe not the same as the entire issue?

This appears to exhibit on the latest pip, btw, so try pip --upgrade pip.

This should now be fixed!

I am going to close this. Feel free to open if its not fixed.

(It won't be fixed until we regenerate the index, but that can wait for the next release.)

I regenerated the index. We don't need to wait for the next release.
