Adjusting sonar issues

Following the application of the patch I saw that we have a small problem for the detail part of the revision, since the theme activated is the admin theme the templates used for the theme of the site are not available the thing that may not display the block perfectly.
Via this patch I propose a small refactoring of the work done by @Nono95230 with the deletion of the page view revision of the theme admin.
Add admin_route option to true, for the following routes :

'entity.block_content.version_history'
'entity.block_content.revision_revert_form'
'entity.block_content.revision_revert'
