The script file must exist in the root of the specified gitea-repo.
You also need to specify (and calculate) a sha256sum output
for that file. This needs to be added as KV pair to
the respective collection in :websites.
Also fixed smaller issues in website.cljc.
Better division of generate-common-*, now these functions
may reside in c4k-common and generate standing ingresses/certs
with only service and fqdn inputs (which need to be set anyways).
Also moved predicates and specs to website.cljc.
