feat: pass platform from env variables or fall back to use old logic

- introduce new env var ODH_PLATFORM_TYPE, value set during build time
  - if value not match, fall back to detect managed then self-managed
- introduce new env var OPERATOR_RELEASE_VERSION, value also set during build time
  - if value is empty, fall back to use old way from CSV to read version or use 0.0.0
- add support from makefile
  - use envstubst to replace version
