Additional Context

@tedchamb Actually it is related to #160 but now for also --merge-commit-message.

I noticed if you don't apply the option to the cli and click 'Set auto-complete', in the background DevOps actually does it by nature. The only thing which is needed is to enable it for the cli also like the description field.

For documentation, the resolution in #160 does not work for this argument:

az repos pr update --id 1234 --auto-complete true --merge-commit-message "Merged PR 1234: commit title" "Related work items: #45678"

responds with:

unrecognized arguments: Related work items: #45678
