glab mr update: -f --fill-commit-body options

Problem to Solve

glab mr create -a laszlo.papp -l mylabel --reviewer foo.bar,hello.world -b 3d-arch -f -y

without -fill-commit-body

This works fine for creating a MR from a single commit, but for multiple commits, the title and description of MR are not very informative.

Proposal

When I do a mistake like above, if I could have glab mr update to have a -fill-commit-body parameter, that would be great.

Additional context

glab mr update id -f -fill-commit-body would be great to have. Does it fit or was it deliberately not implemented?
