fix: Correct URL parameter parsing in execute page

[tanchekwei]

Fix: #1742

The forEach callback for URLSearchParams in src/execute/index.js had its key and value parameters inadvertently swapped.

This resulted in incorrect parsing of URL query parameters, where the intended value was treated as the key and vice-versa.

This commit corrects the parameter order to (value, key), restoring the standard key=value parsing behavior for URL parameters passed to the execute page.

Just spent an hour trying to figure out why I couldn't trigger my workflow, this fixed my issue.
