Change

<tab>Feedback</tab>

to

<tab>ronisbt</tab>

Now looks like:

<?xml version="1.0"?>
<config>
    <tabs>
        <ronisbt translate="label" module="feedback">
            <label>Feedback</label>
            <sort_order>200</sort_order>
        </ronisbt>
    </tabs>
    <sections>
        <feedback_setting module="feedback" translate="label">
            <label>Feedback</label>
            <tab>ronisbt</tab>
            <frontend_type>text</frontend_type>
            <sort_order>1</sort_order>
            <show_in_default>1</show_in_default>
            <show_in_website>1</show_in_website>
