Bug description

On apps pages like
https://my.domain.com/index.php/settings/apps/installed
https://my.domain.com/index.php/settings/apps/enabled
https://my.domain.com/index.php/settings/apps/disabled
https://my.domain.com/index.php/settings/apps/app-bundles

there is a list of apps.

Once app is clicked the right sidebar appears and shows app description with no translation.

It turned out that there was no translation function used in the file in charge (apps/settings/src/components/AppStoreSidebar/AppDescriptionTab.vue)

Once added t(app.id, app.description) into the template there was still no translation

<script setup lang="ts">
...
import { translate as t } from '@nextcloud/l10n'
...
</script>

<template>
  ...
  <Markdown :text=" t(app.id, app.description)" :min-heading="4" />
  ...
</template>

I came up with an idea of importing localization file lazily

<script setup lang="ts">
...
watch(
	() => props.app.id,
	async (id: string) => {
		ready.value = false
		try {
			await import(/* webpackIgnore: true */`${window.location.origin}/apps/${id}/l10n/${language}.js`)
			ready.value = true
		} catch (e) {
			ready.value = false
		}
	},
	{ immediate: true },
)
...
</script>

but I believe there is still a bug in translate function which could have loaded localization file under the hood

Steps to reproduce

1. Go to https://my.domain.com/index.php/settings/apps/installed
2. Click on an app so the right sidebar would appear and show app description
3. See no translation for the app description

Expected behavior

1. Go to https://my.domain.com/index.php/settings/apps/installed
2. Click on an app so the right sidebar would appear and show app description
3. See the app description translated in accordance with selected language
