ok to test

Please remove ./doc-content/shared-kie-docs/src/main/asciidoc/shared/images, it is empty.

[jomarko]

Please remove :imagesdir: attribute from files:

• doc-content/drools-docs/src/main/asciidoc/ReleaseNotes/ReleaseNotesDrools.7.0.0.Final-section.adoc
• doc-content/jbpm-docs/src/main/asciidoc/ReleaseNotes/Release.7.11.0.Final-section.adoc

[jomarko]

You mentioned this change is ongoing, however just for record, update readme.

[jomarko]

Please remove :images:dir attribute from assemblies folder. Given files can be found as:

cd kie-docs/assemblies;
grep -r -i ":imagesdir:";

I believe this can be done because there is no image referenced. Confirmed as:

cd kie-docs/assemblies;
grep -r -i "image::";

[jomarko]

I think just some minor additional cleanup needed, then good to merge.

Thanks @jomarko. Removed empty shared images folder and a couple of stray :imagesdir:. The ones in the assemblies are in fact required. I'll update the README in a separate push, after rebase.
