Change image asset name to fix cutplugin command

[mickmister]

Summary

The asset name zoom-plugin-configuration.png was causing issues with the cutplugin command, likely because it contains the word "plugin". This PR changes the image name to avoid this conflict.

Error while signing plugin
Error: failed to create platform tars: found wrong platform binary in /tmp/zoom-1.7.0.tar.gz1009784493/mattermost-plugin-zoom-v1.7.0-rc1-osx-amd64.tar.gz, expected plugin-darwin-amd64, but found [plugin-darwin-amd64 zoom-plugin-configuration.png]

I don't see where this file (or other files from the assets folder) are being used. I see links in the README like https://github.com/mattermost/mattermost-plugin-zoom/assets/74422101/3928708d-8b57-474b-9c4a-d1e21c054d31 that seem to reference images in the assets folder, though I don't know how to verify which file it's accessing, and I don't know if I will break anything by renaming/removing images files. I don't see the name of the file zoom-plugin-configuration.png (or most of the files in the assets folder) being used anywhere in the repo, so it seems there is nothing using it but I'm not sure.

With regards to the image references in the README, none of them seem to be referencing the checked-in images directly. I'm going to convert the ones being used into checked-in files, and get rid of any checked-in files that are not being referenced in the repository.

I don't want to complicate this PR though. This is meant to unblock the RC build issue
