The built-in Testdoc tool will be removed in RF 8.0 for the reasons explained in #5591 and should be deprecated in RF 7.5. The tasks that needs to be done include:

• Print a deprecation warning when Testdoc is used.
• Add a note about deprecation to the Testdoc section in the User Guide.
• Add a note about deprecation to Testdoc's --help text.
• Mention deprecation in RF 7.5 release notes.

A problem with the note in the User Guide is that we plan to migrate the User Guide content to a new platform. If that's done, it doesn't make sense to migrate Testdoc related documentation because it would be removed already in RF 8.0. If we create further RF 7.4 releases, adding a note to the User Guide at that point is probably a good idea. No deprecation warnings should be emitted until RF 7.5, though.
