publiccode.yml: add genericName, tighten shortDescription

The openCode.de validator flagged 'Generic Name' as the only blocker. Per
the publiccode.yml spec, the genericName field describes the category of
software ('Software xxx is a yyy'), max 35 chars. Set to 'JavaScript
OpenDocument ODF Library' (35 chars exactly).

Also rewrote shortDescription to fit under the 150-char spec limit (was
165 chars, prone to silent rejection by stricter validators) and to
naturally include both 'JavaScript' and 'TypeScript' as separate words
for parser-scraper indexing.

Local German validator confirms the file is now error-free.
