## Summary
Adds a dev docs guide for the core-approved versioning strategy. This
strategy is subject to some iteration but is based on the work we did
for the Saved Objects Management plugin in
https://github.com/elastic/kibana/pull/149495.
Closes https://github.com/elastic/kibana/issues/149929
## How to test
1. Run `./scripts/dev_docs.sh`
2. Navigate to "Versioning interfaces" in the side nav menu
