JSON schema supports @x-plugin null comment.

[samchon]

This pull request updates the handling of jsDoc tags in the JSON schema plugin to support proper casting of the string "null" to the JavaScript null value. It also adds corresponding tests to ensure this behavior is correctly validated.

Enhancements to jsDoc tag value casting:

• Updated the cast function in src/programmers/internal/json_schema_jsDocTags.ts to convert the string "null" to the JavaScript null value, in addition to existing conversions for booleans and numbers.

Testing improvements:

• Added a test in test/src/features/issues/test_pr_1714_json_schema_plugin_by_jsDocTags.ts to verify that the new @x-null-value null jsDoc tag is correctly cast to null in the generated schema.
• Modified the ISomething interface in the same test file to include the @x-null-value null jsDoc tag for the id property.

Version update:

• Bumped the package version in package.json from 11.0.1 to 11.0.2 to reflect these changes.
