app.py: Sort license entries in index.* file by their key

Re-generating the `docs` by utilizing [1] on my machine running Ubuntu
for ScanCode version `31.1.0` produces the same entries for the licenses but
differs in terms of their ordering compared to [1]. This is why I assume
that the ordering is not deterministic, but somehow dependends on the
host system.

Sort the license entries by their license key to ensure a deterministic
order independent of a host system. This leads to nicer diffs for
documentation updates.
