[TASK] Unify YAML in Content Security Policy examples (TYPO3-Document…

…ation#4797)

The strings in the examples are sometimes with or without double quotes, sometimes with a single quote.
This is now streamlined, and double quotes always used.

Please also note, that "static" sources in CSP are always enclosed in single quotes, like `'self'`, resulting in `"'self'"` in YAML.

Releases: main, 12.4
