PHPStan Level 6

[lloc]

PHPStan level 6 focuses on enforcing type hints in PHP code. It's about adding missing type declarations and ensuring that all types are explicitly specified, including array value types and generic types.

Some minor bugs were also fixed:

• echo esc_html_e()
• throw new Error instead of WP_CLI::error in a command
