Fix for new b-tagging collections in EXOT27
This is a replacement for !25401 (closed), from a branch where @jburr has write permissions.
From there:
Some recent merge requests (specifically !25261 (merged)) broke a lot of derivations. This should fix EXOT27.
Attention @cpollard and @jburr. Also relates to ATLASDPD-1334.
