[Buddy] ref_name に正規表現は使える

[srz-zumix]

1. One for all – enter * to run the pipeline for every branch and tag.
2. Only for branches – refs/HEAD/* pattern will run the pipeline for every pushed branch.
3. Only for tags – refs/tags/* pattern will run the pipeline for every pushed tag.
4. Refs name and refs path – patterns can be based on refs, e.g. dev* will run the pipeline for all tags and branches starting with dev. For more control, you can build a pattern on the ref's path, e.g. refs/tags/v* will run the pipeline only for tags starting with v.
5. Regex wildcard – to use regex, the whole pattern should be enclosed in (), e.g. (refs/tags/v.+) will run the pipeline only for tags starting with v, while (^((?!master$).)*$) will run the pipeline for all branches except master.
