chore: remove v prefix from release tags

[marandaneto]

💡 Motivation and Context

This ports the same release-workflow fix from posthog-go to posthog-python. The current workflow hardcodes a v prefix when creating the Git tag and GitHub release, but this repo should use plain semantic versions like 1.2.3.

💚 How did you test it?

• ruby -e 'require "yaml"; YAML.load_file(".github/workflows/release.yml"); puts "yaml-ok"'
• git diff --check

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes.
• I updated the docs if needed.
• No breaking change or entry added to the changelog.

If releasing new changes

• Ran sampo add to generate a changeset file
• Added the release label to the PR
