Jia had a concern that this could still cause confusion, since the sandbox saying v.1.2.0 doesn't mean it's 1.2.0, rather it is 1.2.0 + some commits (potentially several hundred)

so something might work in the sandbox but not work if a user downloads 1.2.0

it might make sense to show a commit timestamp or commit hash instead, set when the website update script runs. for local builds we can show a placeholder or nothing

According to mypy_primer, this change doesn't affect type check results on a corpus of open source code. ✅

Thanks! This LGTM. I had to patch the imported copy of this change to fix our internal build (not the fault of this PR - internal build files aren't exported to GitHub), so I'll have to get a second review before merging.
