Description of work

Removal of FindUBUsingMinMaxD Algorithm as this has been deprecated in 2013.

Summary of work

Remove FindUBUsingMinMaxDs, FindUBUsingMinMaxDTest and associated files from Mantid Code base.

This PR also removes references from CMake and documentation references from v6.1.0 release notes for diffraction.

Part of #31258

Further detail of work

Deprecated as part of commit #b65b56e

To test:

• tests should pass
• Check correct files have been removed (algorithm & tests)
• Check correct lines have been removed from CMake
• Check there are no further links/references to FindUBUsingMinMaxD in the code base

Reviewer

Please comment on the points listed below (full description).
Your comments will be used as part of the gatekeeper process, so please comment clearly on what you have checked during your review. If changes are made to the PR during the review process then your final comment will be the most important for gatekeepers. In this comment you should make it clear why any earlier review is still valid, or confirm that all requested changes have been addressed.

Code Review

• Is the code of an acceptable quality?
• Does the code conform to the coding standards?
• Are the unit tests small and test the class in isolation?
• If there is GUI work does it follow the GUI standards?
• If there are changes in the release notes then do they describe the changes appropriately?
• Do the release notes conform to the release notes guide?

Functional Tests

• Do changes function as described? Add comments below that describe the tests performed?
• Do the changes handle unexpected situations, e.g. bad input?
• Has the relevant (user and developer) documentation been added/updated?

Does everything look good? Mark the review as Approve. A member of @mantidproject/gatekeepers will take care of it.

Thanks for this, I think there are still some references to FindUBUsingMinMaxD in related algorithms that should be removed
