Deprecation of `sdimaging`

[tnakazato]

Since we decided to deprecate sdimaging as of CASA 6.7.0, Relevant casadocs pages must be updated (or removed) as needed.

Hi @tnakazato , looking at CAS-14439, what we probably need to do is add a deprecation warning to the sdimaging task page, and maybe change references from sdimaging to tsdimaging throughout the docs. Then in a future CASA version sdimaging (and all remaining references) to it can be removed from the docs. Is that correct? Please let me know and I can update this directly on CASA Docs.

@bemonts, that is correct. Thank you for your offer! Please update CASA Docs and let me know once you have done.
