feat: schedule daily image builds #111
Description
Is your feature request related to a problem? Please describe.
Images can get out of date quickly. Daily builds will ensure they are always fresh while also testing for breaking changes (e.g. new, official distribution middleware package versions). Wherever possible, versions are explicitly defined to improve consistency.
Describe the solution you'd like
Modify the GitHub Actions workflows that build container images to run daily in addition to their existing triggers.
Describe alternatives you've considered
Allowing the images to get stale is not advisable. Weekly builds could help, but would not provide quick feedback to prevent potential users or contributors from experiencing problems. A maximum potential 24-hour "gap" seems acceptable.
