fix: revert VERSION extraction to handle simple v-prefixed tags

[workos-sdk-automation]

Summary

Reverts the VERSION extraction in release.yml from ${GITHUB_REF_NAME##*/v} back to ${GITHUB_REF_NAME#v}.

The ##*/v pattern requires a / before v to match, so with simple v6.1.0 tags (from the include-component-in-tag: false fix in #441), it returns the full v6.1.0 string instead of 6.1.0, causing gem push to look for pkg/workos-v6.1.0.gem instead of pkg/workos-6.1.0.gem.

Test plan

• Merge this PR
• Delete the v6.1.0 release and tag
• Merge chore(main): release workos 6.1.0 #437 and verify the publish workflow succeeds

Greptile Summary

This PR correctly reverts the VERSION extraction pattern in the release workflow from ${GITHUB_REF_NAME##*/v} back to ${GITHUB_REF_NAME#v}. The ##*/v pattern requires a / before v to match, which doesn't work with simple v6.1.0 tags (only with full refs like refs/tags/v6.1.0). This revert ensures the gem publish step looks for pkg/workos-6.1.0.gem instead of incorrectly searching for pkg/workos-v6.1.0.gem.

• Fixes VERSION extraction to properly strip the v prefix from simple tag names
• Aligns with the tag format change from PR fix: use simple v-prefixed tags and fix gem publish path #441 (include-component-in-tag: false)
• Critical fix to unblock the gem publishing workflow

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The change is a simple, well-understood revert of a bash parameter expansion pattern that fixes a broken gem publishing workflow. The fix correctly handles simple v-prefixed tags (e.g., v6.1.0) by using #v instead of ##*/v. No security concerns, no logic errors, and the change is essential for unblocking releases.
• No files require special attention
