Remove trailing space from dependency license metadata

The dependency license metadata is generated by the "Licensed" tool. Previous versions of this tool added a trailing
space on the `summary` key. Although trailing whitespace in human produced content is not permitted, machine generated
content is used as-is, and so these trailing spaces were left in the metadata files.

It seems that the defect in the "Licensed" tool that caused the trailing space was fixed in a recent version because it
is now absent in the metadata files produced by the tool. The metadata files are hereby updated to use the format of
the version of the "Licensed" tool currently in use.
