Additional notes

[barhanc]

Two questions regarding the additional packages:

• what should we do with react-native-executorch-webrtc; I'm not at all familiar with its backstory and where it is used?
• this PR deletes the workflows for publishing the resource-fetchers to npm, I'm not sure if that's correct?

react-native-executorch-webrtc is a package that was used in fishjam. Precisely, we needed to make a proxy package that would wire our library with fishjam to support selfie segmentation. To decide either we should support it or not, we should contact fishjam team.

Regarding removing flows for publishing, it's okay, since even if we want to publish patches for previous versions, we have them on 0.9, ... release branches.
