build compatibility layer with the bot

[trz42]

Use PRs #163 (bot/build.sh), #166, #167, #168, #169 to build compatibility layer with the bot. Might also look into https://github.com/trz42/compatibility-layer/tree/new_cl_spring_2023 for an attempt to get these PRs working together. The latter may contain a few tweaks necessary on some bot instances.

Made an attempt to build with #177 (see NorESSI#7). Failed with some sync issue (likely a typo in an ansible script). Will rerun the build to check if it works against pilot.eessi-hpc.org/2023.04 and pilot.nessi.no/2023.04.

New attempt is NorESSI#8

Autonomously building the compat layer worked for 2023.06 (cfr. #188), but creating the proper tarball failed because of a bug in the last part of the bot/build.sh script which was added in #163 and tweaked in #177 - cfr. #189

The entire process worked for 2025.06, so I'm closing this issue.
