make the pipeline to post faster

[dannystaple]

Generate thoughts on making it faster:

1. Build and push the builder image - Ie use a cache.
2. Maybe make the builder and staging a 2 stage image.
3. Zip up artifacts between stages might make it quicker.
4. The repo reduction - like the clean up ticket Clean the junk and duplicates in the drafts folder. #3 might make checkouts quicker
5. Sparse checkouts
6. Copy more needed files at the first checkout - other checkout steps might not be needed
7. find a smarter way to wait for things to be up than sleep 10.
8. Bundle the two artifacts into 1 and expand.

Generate some smaller tickets from the best of these, and see how they effect posting performance.

Current timing without improvement is 7 to 8 minutes.

Current timing is 12 minutes.

The longest step is build site - at 7m 25s.
Where is that spending time?

• 2m18s - building the actual site
• 3m54s zipping up the site artifact.
  It is in that artifact so it can be used to deploy and to test. Could I speed it up by putting the actions into a single job (a bit less modular) so it doesn't need to go to and fro with that?

The staging test could be made much faster by adding a container cache - perhaps using the buildx gha cache option. That test is looking at 3 locations in the served output - verifying that htconfig is sane enough.
