Describe the issue

Koji tag f43-build does not allow setting _with_bootstrap macro while equivalent tags for Fedora <= 42 allow this macro.

Reproducer:

$ koji taginfo f42-build | grep sidetag_rpm_macros_allowed
  sidetag_rpm_macros_allowed : '_with_bootstrap'

$ koji taginfo f43-build | grep sidetag_rpm_macros_allowed

Please allow the macro in f43-build tag.
Also fix branching scripts so that future tags like f44-build will allow the macro as well.

When do you need this? (YYYY/MM/DD)

• For fixing f43-build - ASAP (2025/02/26)
• For fixing branching scripts - before branching (2025/08/12)

When is this no longer needed or useful? (YYYY/MM/DD)

N/A

If we cannot complete your request, what is the impact?

Users will have to push extra dist-git commits to toggle the bootstrap macro from spec files.
