Fix CI build failure in release workflow

[antonym]

Summary

• Added fetch-tags: true to checkout action to ensure git tags are available during CI runs
• Added error handling to git rev-list command to prevent script failure when referenced tag doesn't exist

Problem

The release workflow was failing with exit code 129 on the git rev-list command when trying to find commit SHA for version tags that weren't available in the CI environment.

Solution

1. Fetch tags explicitly: Added fetch-tags: true to the checkout action to ensure all git tags are downloaded
2. Error handling: Modified the git rev-list command to gracefully handle missing tags by returning empty string instead of failing

Test plan

• Verified the workflow syntax is correct
• Confirmed the error handling works locally
• Test in CI environment to ensure the build completes successfully
