Describe the bug

Current healthcheck logic doesn't work with OIDC.

Here is the original checks:

if ($httpCode !== 200 || !is_string($content) || !str_contains($content, 'jsonVars') || !str_contains($content, '</html>')) {

For OIDC:

1. httpCode will be 302 (moved)
2. content doesn't contain "json"

This line will work:

if (($httpCode !== 302 && $httpCode !==200) || !is_string($content) || !str_contains($content, '</html>')) {

To Reproduce

1. Enable OIDC
2. Run cli/health.php
3. Get exit code (echo $?)

Expected behavior

Script exit code should be 0
