@uri is not percent-encoding all reserved characters

[dhawal55]

@uri documentation in manual:
Applies percent-encoding, by mapping all reserved URI characters to a %XX sequence.

However, it does not percent-encode certain reserved characters like ! ( ) *.

echo '"!()*#$&+,/:;=?@[]"' | jq -r '@uri' 
!()*%23%24%26%2B%2C%2F%3A%3B%3D%3F%40%5B%5D

The single quote ' is also reserved but not encoded by @uri.
