v7.16.11 (2022-01-20)

This empty releases force-publishes a new version of @babel/plugin-proposal-private-methods (which was not published in v7.16.10 because it didn't have any actual change) and of @babel/preset-env.

This solves an incompatibility between @babel/preset-env@7.16.10 and @babel/helper-create-class-features-plugin@7.16.7, by making sure that @babel/preset-env transitively depends on @babel/helper-create-class-features-plugin@^7.16.10.
