thoth-tech/doubfire-web:doc/readme migration progress update #428

Description

Migration progress has been updated to reflect the current state of the 9.x branch. Files that have been flagged as not used/required within 10.0.x have been separated to make clear that removal has not yet occurred. i.e. the files are still present in both 9.x and 10.0.x as at the time of this PR.

Type of change

• Documentation (update)

How Has This Been Tested?

The updated content has been tested against the thoth-tech/doubtfire-web: 9.x, thoth-tech/doubtfire-web: 10.0.x, doubtfire-lms/doubtfire-web: 9.x and doubtfire-lms/doubtfire-web: 10.0.x branches. The migration_progress script output was also compared however the output results cannot be simply copied across as it does not account for those files completed within 10.0.x.
The actual changes of this PR have been tested through the file previews to ensure the display aligns with existing formatting structures.
