Pull Request Overview

This PR removes encodeURI from the list of recognized sanitizers in request-forgery analysis, so calls to encodeURI no longer suppress alerts.

• Added a test case in serverSide.js to show encodeURI(input) is now flagged.
• Updated the expected alerts in RequestForgery.expected to include the new alert for encodedUrl.
• Modified RequestForgeryCustomizations.qll to filter out encodeURI from being treated as a sanitizer.
• Added a change note documenting the removal of encodeURI.

• [nitpick] Since the analysis comment mentions both encodeURI and encodeURIComponent, update this change note to also mention removal of encodeURIComponent if that exclusion is intended.

* Removed `encodeURI` function from the sanitizer list for request forgery.

• The comment above mentions both encodeURI and encodeURIComponent as not valid URL sanitizers, but only encodeURI is excluded. Consider adding a similar exclusion for encodeURIComponent to match the documentation.

Seems reasonable. 👍
