docs(readme): fix total downloads badge

The release downloads badge from shields.io only checks the first 100
most recent GitHub Releases to calculate the download totals. This
obviously yields invalid values if a repository has more than 100
releases.

Hence we're switching the badge to source it's data from a custom JSON
file in the meta branch, which is updated once an hour but a scheduled
GitHub Actions workflow which runs a Go file that checks all releases
from all pages for downloads counts.
