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 we do not permit trailing whitespace in human produced content, we accept machine
generated content 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 I
see that it is now absence in the metadata files produced by the tool. The metadata files are hereby updated to use the
format of the current version of the "Licensed" tool.
