Currently, lots of warnings are logged during drools-docs antora build.

for example)

{"level":"warn","time":1658993329554,"name":"asciidoctor","file":{"path":"/home/tkobayas/usr/work/DROOLS-7083/drools/drools-docs/src/modules/ROOT/pages/getting-started/first-rule-project.adoc"},"source":{"url":"https://github.com/tkobayas/drools.git","worktree":"/home/tkobayas/usr/work/DROOLS-7083/drools","refname":"DROOLS-7083","startPath":"drools-docs/src"},"msg":"skipping reference to missing attribute: context"}

Findings as of 2022 Jul 28:

• Despite the warnings, the attributes are properly rendered when we view index.html including left pane / right pane navigation
• When we search a word in a search-box (upper-right corner), we will access individual pages. In those pages, the attributes are not rendered. (e.g. {PRODUCT}). This is a problem
• Also many warnings prevent us from finding other issues

So this is not a minor problem but docs contents likely have higher priority.
