Fix privacy request confirmation checkbox alignment

[deepakpra]

What?

Fixes the alignment of the confirmation email checkbox on the Add Data Export Request form.

Why?

The privacy request form was resetting margins for all inputs in src/wp-admin/css/forms.css around line 1578:

.wp-privacy-request-form input {
	margin: 0;
}

This overrode the default checkbox/radio margin declared in the same file around line 126:

input[type="checkbox"],
input[type="radio"] {
	margin: -0.25rem 0.25rem 0 0;
}

As a result, the checkbox in src/wp-admin/export-personal-data.php around line 130 appeared vertically misaligned with its label.

How?

Narrows the privacy request form selector so checkbox and radio inputs keep the default admin form control spacing, while other inputs continue to have their margins reset.

Screenshots

Before	After

Testing Instructions

1. Go to Tools > Export Personal Data.
2. Check the Confirmation email field.
3. Confirm the checkbox is vertically aligned with the “Send personal data export confirmation email.” label.
4. Go to Tools > Erase Personal Data.
5. Confirm the same checkbox alignment still looks correct there.
