fix(blink): cmdline is now top-level on main branch (#5615)

## Description
This `blink.cmp`
[commit](93215d8034)
introduced a breaking change on main branch. `cmdline` is now top-level
and the option is `opts.cmdline.sources = {}`.

I also added a note to remove this hack when the next blink stable
release comes out, which should be greater than current 0.11.0 and just
do it normally in `opts` instead.
