Update license referencing and revise package dependencies

This commit deletes the independent license file in the third-party calendar package and integrates the relevant license referent into the main LICENSE file. It also revises the dependencies across several packages, including removing 'num-traits' from the base workspace dependency, and updating 'chrono' and 'calendar' packages to workspace mode to centralize version management.
