fix(generate-release-description): Fix inconsistent style of the rele…

…ase description content when the project has a single release tag

The `git_log_opts` array variable isn't initialized before being referenced in the single commit if case:

https://gitlab.com/the-common/project-template/-/blob/daebf87b/continuous-integration/generate-release-description.sh#L52

This patch moves the assignment of the `git_log_opts` array variable at

https://gitlab.com/the-common/project-template/-/blob/daebf87b/continuous-integration/generate-release-description.sh#L107

before the `if` built-in command call.
