(docs/hotfix): track latest release by SemVer

- "latest" in GitHub releases means latest by date, which means
  backports are considered latest by definition
  - currently 0.1.11 is showing as latest :/
    - using SemVer with the "tag" badge (not release anymore :/)
      more or less resolves this for the README, but GH releases page
      will always show by date :/

- "commits since" is also currently tracking "latest" release by date
  - no fix to this yet, c.f. badges/shields#1955 (comment)
    - manually putting the latest SemVer tag for now :/ :/ :/ :/
