Mutating prop in request-public component

[krmax44]

This component is mutating a prop using v-model:

froide/frontend/javascript/components/makerequest/request-public.vue

Line 4 in f94499b

<input type="hidden" name="hide_public" v-model="hidePublic" id="id_hide_public"/>

ESLint will treat this as an error, I added an exception in #497

froide/frontend/javascript/components/makerequest/request-public.vue

Lines 4 to 11 in 5bdc784

	<!-- FIXME: shouldn't be mutating props -->
	<!-- eslint-disable vue/no-mutating-props -->
	<input
	type="hidden"
	name="hide_public"
	v-model="hidePublic"
	id="id_hide_public" />
	<!-- eslint-enable vue/no-mutating-props -->
