feat: Upgrade jsonlint to get better JSON Schema support

BREAKING CHANGE: Dropped support for Node.js 12 . The minimum supported version is Node.js 14.
* The default environment recognises only JSON Schema drafts 06 and 07 automatically. Not 04 any more. The environment for JSON Schema drafts 04 has to be selected explicitly. Also, JSON Schema drafts 06 and 07 are handled by AJV@8 instead of AJV@6. It shouldn't make any difference, but the implementation is new and could perform a stricter validation.

+* Supports [JSON Type Definition].
 * Optionally recognizes JavaScript-style comments and single quoted strings.
 * Optionally ignores trailing commas and reports duplicate object keys as an error.
 * Can sort object keys alphabetically.
 * Offers pretty-printing including comment-stripping and object keys without quotes (JSON5).
-* Prefers using the 7x faster native JSON parser, if possible.
+* Prefers using the 10x faster native JSON parser, if possible.
 * Formats column number of error occurrences too, does not report error location twice.
 * Prints the same rich error information for schema validation.
 * Depends on up-to-date npm modules with no installation warnings.

 * `schema`, when set the source file will be validated using ae JSON Schema in addition to the syntax checks
 * `src`, when filled with a file path, the file will be used as a source of the JSON Schema
-* `environment`, can specify the version of the JSON Schema draft to use for validation: "json-schema-draft-04", "json-schema-draft-06" or "json-schema-draft-07" (if not set, the schema draft version will be inferred automatically)
+* `environment`, can specify the version of the JSON Schema draft to use for validation: "draft-04", "draft-06", "draft-07", "draft-2019-09", "draft-2020-12" or "jtd" (if not set, the supported schema draft versions will be 06 and 07)
