feat(release): update semver install version

Changes:

- Updated the `go install` command to specify a fixed version of `semver` (v2.8.0) instead of using `latest`.
- This ensures that the release script will use a consistent version of the `semver` tool, avoiding potential issues with breaking changes in future releases.
