Describe the bug you're encountering

The bug is follow up of the by reported for SwaggerUI swagger-api/swagger-ui#9304 where it causes the practical problem.

Calling the sanitize() function in https://github.com/swagger-api/apidom/blob/main/packages/apidom-reference/src/util/url.ts#L248 cause double encoding when URL already contains encoded 'special' symbols: ; / ? : @ & = + $ , #

To reproduce...

Steps to reproduce the behavior:

1. Call sanitize() function with URL that contains encoded symbols %2F , %3B etc. Similar to test case https://github.com/swagger-api/apidom/blob/main/packages/apidom-reference/test/util/url.ts#L294 . For example sanitize('https://example.com/path%20with%20spaces%2Fslashes%3Bsemicolons/?including=in%3Fparameters')
2. The expected output is the same URL: 'https://example.com/path%20with%20spaces%2Fslashes%3Bsemicolons/?including=in%3Fparameters.
   The real output is this: https://example.com/path%20with%20spaces%252Fslashes%253Bsemicolons/?including=in%253Fparameters .
   The % of the %2F and %3B are encoded. It should not happen.

Expected behavior

The encoded URL passed to sanitize() should remain the same for all possible combinations of encoded symbols

Additional context or thoughts

The reason for the issue is that decodeURI() and encodeURI() leave 'special' symbols ; / ? : @ & = + $ , # encoding unchanged. It is mentioned in the documentation at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURI#description and https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURI#description .
