ICU4X Github Actions Generated Files

This branch is for persistent files generated by Github Actions. For example, the file persistence is needed by the Continuous Integration benchmark action to construct the graphs with historical information. See Continuous Integration and Builds or CI workflows in .github/workflows for more details.

The ICU4X API documentation webpages are not in this branch, but are auto-generated and copied by CI to: https://github.com/unicode-org/icu4x-docs
