Fix parse_query decoding multiple plus signs

[mugiwaraluffy56]

This fixes the JavaScript implementation of uri.parse_query so all plus signs in query keys and values are decoded as spaces, matching the Erlang target.

The previous JavaScript implementation used String.prototype.replace, which only replaced the first plus sign. This now uses replaceAll and adds a regression test for multiple plus signs in both the key and value.

Verification:

• git diff --check
• Node expression confirmed replace only handles the first plus while replaceAll handles all plus signs
• Erlang uri_string:dissect_query confirmed the expected decoded result

hey @lpil, I thought one PR at a time would be a good practice, so that’s why I closed this 😅.
