Make compile Make target output less noisy

What does this MR do and why?

Follow up to: !3874 (merged), just to make the debug output as concise as possible.

• @ stops the command itself being echo'd (we have a few instances of that).
• --no-print-directory passed to make stops it reporting what directory it's in.

How to set up and validate locally

1. Configure a local GitLab Docs environment: https://gitlab.com/gitlab-org/gitlab-docs/-/blob/main/doc/setup.md.
2. Run make compile with both search backends and note the make output.
3. Check out this branch and run make compile with both search backends. Note the make output is reduced.
