BootstrAPI 0.9.0

This is a BREAKING release. Since BootstrAPI is still in a early development stage, I allow myself to make breaking changes in minor versions. The REST API has changed as described and documented in #114. The release also contains two new endpoints; a settings/banner endpoint for Jira and a settings/custom-html endpoint for Confluence. Also, it's now possible to download snapshot builds for the main branch and merge requests.

What's Changed

• Separate endpoints for single and multiple entities by @pathob in #114
• Workflow: Archive packaged artifacts by @pathob in #116
• Jira: Allow setting announcement banner by @pathob in #115
• Confluence: Allow setting custom HTML by @pathob in #117
