[BUG] Please remove inline onchange JS for resultsPerPage to work with CSP

[georgringer]

Describe the bug The default templates with `onchange="this.form.submit()" fails with CSP

To Reproduce Having CSP in FE configured, try to use the resultsPerPage toggle

Expected behavior Working itemsPerPage setting with CSP

it would be even ok to use a vanilla JS and using inline JS using the native VH of fluid to add a nonce
