Remove/Replace Embedded Node Type

[whizzzkid]

Embedded node types will not be supported in Mv3, Helia in service-worker context can provide an alternative, however service-workers in chrome-extension mv3 has its own limitations: w3c/webextensions#72 The biggest ones are the lack of webRTC streams and webSockets.

More work will be needed to explore this.

I like the idea of replacing, but that's a bigger endeavor. Do we instead just break this into two steps:

1. Remove embedded/js-ipfs
2. Add something better back in

Basically, if it's not a lot of work to remove, lets make our maintenance burden lighter by get rid of code that isn't tested and isn't supported anymore.

@BigLep agreed, I think this can be removed only for chrome mv3, as this would still work in firefox. However, just to be consistent, this can be removed everywhere. Should the UI also reflect this (by removing the entire section to configure this) I think we can leave that as-is till we have more node types.

Tasks:

• Remove js-ipfs
• Remove custom icons for JS.
• Remove references to embedded node-type.
• Remove UI options. (optional)

@whizzzkid : I think we should remove it everywhere. We're not able to support it in Firefox if users have issues. I assume it also cleans up the code to to remove it everywhere. Lets definitely remove it from docs and UI as well. It's not clear at this point if/when we'll replace it with Helia, so I think better to be accurate to where we are.
