chore!: bump celestia-app to v1.0.0-rc13

[evan-forbes]

Overview

bumps app to v1.0.0-rc13, core to v1.26.2-tm-v0.34.28, the sdk to v1.18.0-sdk-v0.46.14, and nmt to v0.19.0

per release notes: this is a consensus breaking change that is targetting mocha-4 and arabica-10

besides the already mentioned changes, this bumps app to go 1.21 🎉 and has the simplified programmatic transaction signing repo (we got rid of the KeyringSigner since it was originally designed for tx malleation). This package can be found here, and there are a few (hopefully straightforward) examples here, here, and here. When you all are ready, we'd like to remove the KeyringSigner, and would be delighted to help migrate.
