SHIP-125: update circleci.bash for GitLab migration

[ramandeepromana]

Summary

• Update CI clone URL from GitHub to GitLab for the GitHub-to-GitLab VCS migration
• Replace GitHub API tag lookup with local git tag -l (simpler, no auth, no rate limits)
• Phase 1 of migration: CI-critical changes only, merged before mirror break

Changes

scripts/circleci.bash

• Clone URL (line 5): github.com/2600hz/monster-ui -> gitlab.com/oomaforbin/oomacorp/2600hz/monster-ui -- points CI at GitLab as the source of truth
• Tag lookup (lines 13-17): Replace curl https://api.github.com/repos/2600hz/monster-ui/git/refs/tags | jq with git tag -l | sort --version-sort | grep | tail -1 -- uses locally fetched tags instead of GitHub API, eliminating auth requirements and rate limit concerns

Test Plan

• Verify git tag -l | sort --version-sort | grep "^5.4" | grep -E '^[0-9]+\.[0-9]+\.[0-9]+' | tail -1 returns the correct latest tag for a release branch
• CI build on this branch should clone from GitLab and resolve the correct core version tag
