hugo: update to 0.115.3.

0.115.{3, 2, 1}: bugfixes.

0.115.0
The notable new feature in this release is that you can now have permalink
configuration also for section and taxonomy pages.

0.114.0
The main new thing in this release is that we now support both major versions
of the Dart Sass Embedded protocol, which means that you now can use the
regular Dart Sass binary.
We have also moved to a new log library and added some new math functions and
also revised the existing set to work better with a mix of scalars and slices.
