chore: celestia bridge

[shane-moore]

Changes

• Celestia bridge was added using details noted in slack convo
• note that potential changes are possible, pending our first ibc transfer. any changes will be noted in the slack channel.

Note

• the packages in this PR should be yarn linked to hub in order to test the bridge out, after the first IBC transfer to Injective. This is because we need the denom to exist in the bank module for hub bridge to recognize the new denom

Merging this, we can try when the relayer is up.
