podman images --filter: documented filters don't work

[edsantiago]

`podman-images(1) lists a number of filters, some of which (a) don't show up in command completion, and (b) don't work:

podman/docs/source/markdown/podman-images.1.md.in

Lines 32 to 47 in e8c4d79

$ ... digest=sha256:f5a99
Error: invalid value "sha256:f5a99" for digest filter: invalid checksum digest length
$ ...okay, it works if I `podman image inspect f5a | gron | grep Digest` and copy/paste that

intermediate

$ bin/podman images --filter intermediate=true
Error: specifying "intermediate" filter more than once with different values is not supported

(it works with --intermediate=false but that doesn't seem useful)

manifest[=true/false] works, but does not show up in autocompletion.

Options that don't work should be fixed, or removed from man page.

All valid options should appear in autocompletion.

Documentation vs autocomplete is now fixed (#19987). This is now a functionality bug, so I've removed the documentation label.
