Add Ontology & Semantic Interoperability as a top-level current effort
with links to discussions apache#22, apache#101, apache#108, apache#68 and PRs apache#124, apache#125.

Update existing sections with recently opened discussions, PRs, and
converters: metric trees (apache#40), primary key semantics (apache#15, apache#119),
reusable datasets (apache#103, apache#109), datatype/is_time reframe (PR apache#113),
spatial dimension types (apache#114), default_aggregation (apache#115), positive
direction (apache#41), physical metadata (apache#110), and new converter PRs for
Salesforce (apache#118), dbt (apache#116), and Databricks (apache#120). Also adds
CONTRIBUTING.md (apache#122) and working groups page (apache#123) to Developer
Experience, and lists merged converters as existing artifacts.
