Issue:
Add ISO-15924 validation
## Description

Hello, I'm a core member of the [@faker-js/faker](https://github.com/faker-js/faker) library.
We already use many of your validation methods to verify the integrity of our generated fake values.

For our newest addition, we want to verify codes for the representation of the names of scripts. Those are standardized by [ISO-15924](https://en.wikipedia.org/wiki/ISO_15924).

## Suggested Validation

Validator name: `isISO15924(str)`
Validator Description: Check whether or not the string is a valid 4 character, ISO-15924 script code.

## Additional Information

- [Wikipedia Entry](https://en.wikipedia.org/wiki/ISO_15924)
- [Offical Unicode Website](https://www.unicode.org/iso15924/iso15924-codes.html)

I'm willing to open a PR that integrate this feature if it get's approved.

Hints from issue comments:
@WikiRik: Go for it! Looking forward to the PR@xDivisionByZerox: Wow, that was fast.
Thank you.@xDivisionByZerox: Hi @WikiRik, this Issue and the related PR are open for more than 8 months now. Is there anything I can do to help this moving forward? No pressure from my side, but I want to now what is going on 😄 @WikiRik: I seemed to have missed the PR being opened, I will take a look at it. I do not have the rights to get it merged or anything so I can't really speed up that process. See also the recent discussion here; #2376@xDivisionByZerox: Thank you for picking this one up. Again, there is no pressure from my side. I simply did a quick review on all my open PRs/Issues and tried to move them forward. 

I was not aware of the situation of this project. I'll see if I can take part in the discussion, as my team and I use this library quite often.

+# Contributing to validator.js
+Welcome to validator.js repository!! We appreciate your interest in contributing to this open library and for helping our community grow. 
+
+## How to Contribute
+### Code Contribution
+In general, we follow the "fork-and-pull" Git workflow.
+
+1. [Fork](https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project) the repository on GitHub
+2. Clone the project to your local machine
+3. Work on your fork
+    * Make your changes and additions
+        - Most of your changes should be focused on src/ and test/ folders and/or [README.md](https://github.com/validatorjs/validator.js/blob/master/README.md).
+        - Files such as validator.js, validator.min.js and files in lib/ folder are autogenerated when running tests (npm test) and need not to be changed **manually**.
+    * Change or add tests if needed
+    * Run tests and make sure they pass
+    * Add changes to README.md if needed
+4. Commit changes to your own branch
+5. **Make sure** you merge the latest from "upstream" and resolve conflicts if there is any
+6. Repeat step 3(3) above
+7. Push your work back up to your fork
+8. Submit a Pull request so that we can review your changes
+
+#### Run Tests
+Tests are using mocha. To run the tests use:
+
+```sh
+$ npm test
+```
+

-In general, we follow the "fork-and-pull" Git workflow.
-
-1. Fork the repo on GitHub
-2. Clone the project to your own machine
-3. Work on your fork
-    1. Make your changes and additions
-        - Most of your changes should be focused on `src/` and `test/` folders and/or `README.md`.
-        - Files such as `validator.js`, `validator.min.js` and files in `lib/` folder are autogenerated when running tests (`npm test`) and need not to be changed **manually**.
-    2. Change or add tests if needed
-    3. Run tests and make sure they pass
-    4. Add changes to README.md if needed
-4. Commit changes to your own branch
-5. **Make sure** you merge the latest from "upstream" and resolve conflicts if there is any
-6. Repeat step 3(3) above
-7. Push your work back up to your fork
-8. Submit a Pull request so that we can review your changes
