fix(ios-build-number): filter build number tag by build_type

[robdeans]

When fetching the build number on iOS, we are neglecting to pass the build_type param which if provided will filter the tags based on environment.

Currently: with no filter provided, the most recent build number is fetched and incremented regardless of the environment.

**Start**
Production/Snapshot-100
...
Snapshot-101
Snapshot-102
Production-103
Snapshot-104
Production-105

Expected behavior: build numbers should increment based on their respective environments

**Start**
Production/Snapshot-100
...
Snapshot-101
Snapshot-102
Production-101
Snapshot-103
Production-102
