chore(transport-interop): add js-libp2p v0.46.21

[maschad]

Also upgrade the dependencies

[maschad]

@p-shahi would you remind giving this a review?

[mxinden]

Looks good to me. Though I have limited knowledge of js-libp2p only. Maybe @achingbrain can give a final approval?

[achingbrain]

LGTM, a couple of questions about dep versions inline

[maschad]

@achingbrain I've updated this PR to v0.46.14 so that we can test out the webRTC fixes in #310

[maschad]

friendly ping @achingbrain

if there are no objections here @mxinden I think we can proceed with merging so that we can enable the webRTC tests as mentioned in #310

[achingbrain]

libp2p@0.46.17 has shipped, it'd be good to test with that and all the latest patch releases of the other libp2p modules, otherwise all good from me.

[achingbrain]

I think we should remove the package.json deps that aren't in direct use by this project, as they are currently the same ranges as versions the @libp2p/multidim-interop module depends on so are redundant, but I don't want to block this any further ahead of demoing this week.
