For a list of other open source components included in PR Size Labeler, see the
subfolders in the node_modules folder.
The licenses of those components can be found in the LICENSE file of their respective
subdirectory.
Unfortunately, the dependency tr46 does not contain a license file in the version that we depend
on, but it names the license "MIT" in its package.json.
We thus include a license file from a later version of the library as
tr-46-license.md.
