dnsapi/deploy: remove POSIX character classes from sed/grep patterns
Solaris /usr/bin/sed and /usr/bin/grep parse [[:space:]] etc. as a
literal bracket set and silently mis-match. Replace with [ ]* for
JSON matching, a printf-tab bracket for user-input trimming, and
[0-9] for digits; also drop GNU-only sed -r/-E in rage4, selfhost
and selectel, and reuse _strip_blank_lines in byteplus_alb.
Debug logs occasionally contain private keys or tokens (issue 6267);
the code-side leak in the haproxy hook was fixed by #6268, this adds
the missing warning to the auto-comment that asks for logs.
Runs le_test_nginx from acmetest against Pebble: nginx listens on
Pebble's HTTP-01 validation port with an aaPanel/BT style
"location ^~ /" reverse proxy block, the regression case of #6125.
- replace deprecated set-output with GITHUB_OUTPUT
- untap aws/tap before brew install to silence tap trust warning
- inject safe.directory=* for cygwin git so the checkout post step
no longer fails with dubious ownership (exit 128)
Introduced a new OpenIndiana job to the DNS GitHub Actions workflow for testing, including necessary environment variables and steps. Updated README to display the OpenIndiana workflow status badge.
