Can we get (or is there) an upstream 0.6.z version of foreman-maintain with this fix in it?

Verified.

Tested on Satellite 6.8.3 Snap 1
Version: rubygem-foreman_maintain-0.6.14-1.el7sat.noarch

Setup:
1. # hammer role create --name test_role
2. # hammer filter available-permissions
3. # hammer filter create --role test_role --permission-ids 62,68  (Here id's 62 and 68 are for view_hosts and console_hosts respectively)
4. # hammer filter list --search role=test_role (Check for the role, resource type, and permissions assigned)
5. Change resource type of any permission to test this check -
   # sudo su - postgres -c "psql -d foreman -c 'UPDATE permissions SET resource_type = '\''xyz'\'' WHERE name = '\''console_hosts'\'';'"

Steps:
1. # foreman-maintain health check --label corrupted-roles

Observation:
The check was able to detect and fix the corrupted-roles along with it also displayed their names as well.
Also, After the resource type is changed so it tries to split the filter while splitting out of 2 only 1 permission was changed so it created a new filter for it, and check that with the command `# hammer filter list --search role=test_role`
