Add ability to format bytes as metric or IEC; affects [bundlejs bundlephobia ChromeWebStoreSize CratesSize DockerSize GithubRepoSize GithubCodeSize GithubSize NpmUnpackedSize SpigetDownloadSize steam VisualStudioAppCenterReleasesSize whatpulse] (#10547)

* add renderSizeBadge helper, use it everywhere

- switch from pretty-bytes to byte-size
- add renderSizeBadge() helper function
- match upstream conventions for metric/IEC units
- add new test helpers and use them in service tests

* unrelated: fix npm unpacked size query param schema

not strictly related to this PR
but I noticed it was broken

* chromewebstore: reformat size string, test against isIecFileSize
