build and install cog 0.18.4 in the container

[escherstair]

The official cog package for Debian bookworm is stuck to 0.16.1 and it won't be updated (see here).
For this reason I opened a PR to build the latest cog (v0.18.4) inside the container.

If this way of building works, we can try to see if it's worth rebuilding the latest stable wpewebkit too, as suggested here.

If I use the torizon/cog:3.4.0-20240910 container running on my Verdin iMX8M-Plus I can successfully build and install cog, with the commands suggested from Igalia developers here.
For wpewebkit I'm not able to do the same (see here) because the compilation of wpewebkit takes hours and can't get to a successful end.

For this reason, following this suggestion on Toradex Community I tried using torizon/torizon-deb-ci Action to build the deb packages of cog 0.18.4 and wpewebkit 2.46.1 before including them in a container.
For this reason I created two repos:

• cog-deb
• wpewebkit-deb

and I configured the Github Action to build the .deb packge
The situation is weird:

• for cog, the same commands that works on the torizon/cog:3.4.0-20240910 container fails with the following error

  Some packages could not be installed. This may mean that you have

  The following information may help to resolve the situation:
  
  The following packages have unmet dependencies:
   builddeps:././ : Depends: libwpewebkit-2.0-dev but it is not installable
  E: Unable to correct problems, you have held broken packages.
  Error: Process completed with exit code 100.

  see the output from the github action here even if I tried installing cog manually inside the debian container used by the Action (to match as much as possible the torizon/cog container)
• for wpewebkit, it seems to me that the build action is canceled after more than 6 hours (see here). Maybe the free github plan doesn't allow so long actions?

@microhobby can you help me finding what happens here?
