FR: highlight change ids in rebase advice

[jyn514]

Is your feature request related to a problem? Please describe.
when i rebase, i want to be easily resolve the conflicts. jj shows some helpful advice for this:

To resolve the conflicts, start by updating to the first one:
  jj new vwymzkuxkvrw
Then use `jj resolve`, or edit the conflict markers in the file directly.
Once the conflicts are resolved, you may want inspect the result with `jj diff`.
Then run `jj squash` to move the resolution into the conflicted commit.

however, unlike most of jj's output, the change IDs are not colorized, which means i can't just type jj new u; i have to run jj log first to figure out the short name of the change ID (or copy-paste the long name):

Describe the solution you'd like
colorize change IDs in the "To resolve the conflicts" output.

Describe alternatives you've considered
