[minor stuff] api.json update for tag

[Andrew Anisimov]

Tag 1.5.1 created, but api.json still contains version 1.5.0.

Expected is: api.json to contain the exact tag version.

Possible solution is to re-generate api.json before creating new tag (via some pipeline script).

Thank you for this note, we are gradually automating CI/CD for v1, will definitely do that in the next steps
