Can we include capturing logs of pgdata/pg_upgrade_output.d/*/log in buildfarm

Hi,

Recently there have been few upgrade tap test failures in buildfarm
like in [1] & [2]. Analysing these failures requires the log files
that are getting generated from src/bin/pg_upgrade at the following
locations:
tmp_check/*/pgdata/pg_upgrade_output.d/*/*.txt - e.g.
tmp_check/t_004_subscription_new_sub1_data/pgdata/pg_upgrade_output.d/20240214T052229.045/subs_invalid.txt
tmp_check/*/pgdata/pg_upgrade_output.d/*/*/*.log - e.g.
tmp_check/t_004_subscription_new_sub1_data/pgdata/pg_upgrade_output.d/20240214T052229.045/log/pg_upgrade_server.log

First regex is the testname_clusterinstance_data, second regex is the
timestamp used for pg_upgrade, third regex is for the text files
generated by pg_upgrade and fourth regex is for the log files
generated by pg_upgrade.

Can we include these log files also in the buildfarm?
