added theme: nella-red

[allenfrostline]

New theme developed in order to make utterance comment area more consistent with my blog's overall theme. Changes in yarn.lock not necessarily need merging though.

Thanks for the theme- could you make a couple of changes:

1. Remove the lock file from the PR
2. Add the theme to end of the list of options in the configuration component:
   

   utterances/src/configuration-component.ts

   Lines 129 to 136 in ad0d56c

   	<select id="theme" class="form-select" value="github-light" aria-label="Theme">
   	<option value="github-light">GitHub Light</option>
   	<option value="github-dark">GitHub Dark</option>
   	<option value="github-dark-orange">GitHub Dark Orange</option>
   	<option value="icy-dark">Icy Dark</option>
   	<option value="dark-blue">Dark Blue</option>
   	<option value="photon-dark">Photon Dark</option>
   	</select>

@jdanyow Hi can you merge this PR when you've got time plz? It's been a whole month and my website updating is postponed basically because of lack of this theme for utterances. Thanks a lot 🤖

Hi I think I've delete that file from commit. Can you explain why it's not addressed yet? Thanks

You've got conflicts in 2 files. Probably need to do a rebase to resolve the issues. Probably editing the commits to remove the changes to the lock-file would be easiest
