Make the bookmarking process in android app using the headphones/tws completely handsfree.

### Description

Currently, when we tap on our headphones to bookmark the timestamp while listening to a podcast, it asks us to "name the bookmark" instead of assuming a default name and bookmarking it automatically without needing the user to touch the screen. This defeats the purpose of a complete hands free bookmarking experience which could be VERY useful while doing other activities (chores, running, workout, etc.). Here's my reddit post for the same. https://www.reddit.com/r/pocketcasts/comments/1kcxzmg/whats_the_point_of_bookmarking_hands_free_with/

Would love if this bookmark popup is removed. Thanks a lot.

Start by tracing the Android headphones/TWS bookmark action and the "name the bookmark" popup described in the issue. Done means a headphone tap creates a bookmark with a default name without requiring screen interaction; verify the behavior while listening to a podcast.
