quiet default ansible-doc integration test output (#79921)

* quiet default ansible-doc integration test output 

* typical non-verbose output was exceeding 27k lines per fun
* disables `set -x` unless `-v` is passed to the script (eg when ansible-test is called with `-v` or `--retry-on-error` adds it on the second try
* added simple progress echoes
* suppress some grep output

* only enable `set -x` for >= `-vvv`

* fix shellcheck default complaint
