In addition to the existing plugin 0.4.5 tags, we also want to publish tags to make it easier to find the latest plugin compatible with a given RHDH 1.y release.

• 1.7.0--0.4.5
• 1.7.0 (floating)
• 1.7 (floating)
  ...
• 1.7.1-0.4.6
• 1.7.1 (floating)
• 1.7 (floating,replaced)
  ...
• 1.8.0--0.6.0
• 1.8.0 (floating)
• 1.8 (floating)

Impacted:

• tekton tasks to export+publish need to be updated to produce more than one tag
• plugin_builds.json does not need to be updated; we can just track the plugin version, not the RHDH version as that's implied by the branch
• https://gitlab.cee.redhat.com/releng/konflux-release-data/-/merge_requests/8158/diffs#5c40fb398d9195ae1f2b70f63179dc4add28c341_0_60 - RPAs need to have a different tagging scheme
