fix: Instagram audio rendering issues (#9957)

We are using `audio` component for rendering audio files in dashboard.

```
<audio v-else-if="isAudio" controls>
   <source :src="`${dataUrl}?t=${Date.now()}`" />
</audio>
```
We have added the timestamp for every audio URL for cache busting. For
Instagram, we are getting a signature URL. When we add any value and
access the URL, it results in an "Invalid signature. If I remove the
timestamp, the audio is rendering properly. This PR will change the
logic to construct the URL properly instead of direct string
manipulation.
