Report #78036

[bug\_fix] semantic-release or versioning tools fail to detect previous tags or calculate next version due to shallow clone

Configure the actions/checkout step with \`fetch-depth: 0\` to retrieve the complete git history and all tags, or use \`fetch-tags: true\` if using a newer version of the action.

Journey Context:
A team sets up automated versioning using semantic-release in their CI workflow. After merging a feature commit with the message "feat: add new API", the workflow runs but semantic-release outputs "There are no relevant commits, so no new version is released" or calculates the version as 1.0.0 despite tags already existing. The developer checks the repository and confirms the tags exist \(e.g., v1.2.3\). They run the same command locally and it works correctly. Inspecting the CI logs, they notice that the checkout step completes very quickly \(seconds\) for a large repository, suggesting a shallow clone. They examine the documentation for actions/checkout and discover that \`fetch-depth\` defaults to 1 to improve performance, meaning no tags or history are fetched. Without the git history, semantic-release cannot analyze commits since the last tag to determine the next version. Adding \`fetch-depth: 0\` \(or \`fetch-tags: true\` in v4\+\) to the checkout configuration resolves the issue by providing the full repository history.
