Merge bitcoin#31621: doc: Update dependency installation for Debian/Ubuntu

160c27e doc: Update dependency installation for Debian/Ubuntu and CI (Adlai Chandrasekhar)

Pull request description:

  This is similar to the recently-pushed 8d20348 and results in slightly cleaner systems for future Debian/Ubuntu builds.

  According to the description for pkg-config, "pkgconf is a replacement for pkg-config, providing additional functionality while also maintaining compatibility. This package only provides a dependency link to the pkgconf package to help with package upgrades. It can be safely removed."

  Thus the relevant sections of `doc/build-unix.md` and `depends/README.md` are updated.

ACKs for top commit:
  maflcko:
    weak ACK 160c27e
  fanquake:
    ACK 160c27e - seems correct for modern distro versions, and using pkgconf on older ones also seems to work fine.
