Subject: [PATCH] Bootstrap/Load: Check `$_SERVER['SCRIPT_NAME']` exists before
 passing to `strpos()` in `wp_fix_server_vars()`.

If `SCRIPT_NAME'` does not exist (which can happen in cron jobs), the following happens:

* PHP 8.1+:
    * `Warning: Undefined array key "SCRIPT_NAME"`
    * `Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated`
* PHP 8.0: `Warning: Undefined array key "SCRIPT_NAME"`
* PHP 5.6-7.4: No warning or notice

This commit checks if the key exists before passing it to `strpos()`. This resolves the warning, notice, and future error.

Follow-up to [3034], [3069], [12732].

Props audrasjb, costdev, hellofromTonya, karpstrucking, mcjambi, sergeybiryukov.
Fixes #54142.
