0.64.3 is missing from the matrix.

Trying to use the upgrade tool on a project using react-native version 0.64.3 results in a 404:

info No version passed. Fetching latest...
(node:292856) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency
(Use `node --trace-warnings ...` to show where the warning was created)
info Fetching diff between v0.64.3 and v0.67.2...
error Fetch request failed with status 404: 404: Not Found.
error Failed to fetch diff for react-native@0.67.2. Maybe it's not released yet?
info For available releases to diff see: https://github.com/react-native-community/rn-diff-purge#diff-table-full-table-here

RN 0.64.3 appears to have been released sometime between 0.66.2 and 0.67 (security update?), so perhaps it was missed somehow.
