fix: patch undici File support on Node.js < 20 (#588)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **New Features**
* Improved compatibility for certain environments by adding polyfills
for file handling and Unicode string methods.
* Enhanced string handling with new methods for checking and converting
to well-formed Unicode strings.

* **Style**
* Minor formatting adjustment for improved code readability (no impact
on functionality).

* **Bug Fixes**
* Disabled a specific test assertion related to multipart/form-data
header validation to prevent false test failures.

* **Chores**
* Added ESLint rule to warn when native objects are extended, promoting
better code practices.
