feat!: support eslint v10

[aladdin-add]

This pull request updates documentation and configuration files to introduce and document a new all configuration that enables all rules, and to clarify usage of the mixed-esm-and-cjs config. It also updates examples to use the latest ESLint flat config format and improves the clarity and consistency of rule documentation.

The most important changes are:

Documentation updates for new configs:

• Added documentation for the new all configuration, including its symbol 🌐 in the rules table and config list, and clarified that it enables all rules but is not recommended for production use. [1] [2] [3] [4] [5] [6] [7]
• Updated the FAQ and usage examples in README.md to use the new mixed-esm-and-cjs configuration (now without the flat/ prefix), and updated code samples to use the modern ESLint flat config with ESM syntax. [1] [2]

Configuration file changes:

• Updated .eslint-doc-generatorrc.js to ignore the new mixed-esm-and-cjs config and removed emoji mappings for several flat configs, reflecting the new config structure. [1] [2]

These changes make it easier for users to understand and use the new all and mixed-esm-and-cjs configurations, and ensure that documentation and configuration files are consistent with the latest ESLint best practices.
