Extend the config validator to list issues with locations

Currently, the config validator throws an error if the config is invalid. However, we can enhance it by assigning exact locations to the errors and linking these locations to specific error messages. This would enable the VSCode extension to highlight configuration issues directly in the editor. Reference: https://github.com/AdguardTeam/VscodeAdblockSyntax/issues/146

For this, it may be necessary to replace the YAML parser with the following one: [https://www.npmjs.com/package/yaml](https://www.npmjs.com/package/yaml).

For parsing JSON with locations, we should take a look at https://www.npmjs.com/package/@humanwhocodes/momoa or https://www.npmjs.com/package/json-to-ast
