Allow navigation in embark from consult-gh searches similar to consult-grep

[ParetoOptimalDev]

Is your feature request related to a problem? Please describe.

Yes, being able to sift quickly through github code search results.

The embark functionality introduced in #69 and #70 works great and improves this a lot.

Describe the solution you'd like

Navigating search results with n/p in embark buffer generated from consult-gh-code-search using complilation mode like consult-grep.

When I made my original request, I had assumed the functionality that happens with consult-grep of being able to hit n to go to the next result and having it open in a buffer beside is really smooth.

here is a gif to demonstrate:

Describe alternatives you've considered

Just using the buffer as is, but more manually calling =n= and =RET= myself more.
