Remove stellar_core_commander and update bundler (#3504)

Remove stellar_core_commander and update bundler version and xdrgen.

Mostly to fix xdrgen in this repo for new Ruby versions.

Stellar_core_commander has really old dependencies which are no longer supported on the latest version of Ruby. Also, according to internal discussions we don't actually use stellar_core_commander anymore.

Bundler is being updated because v1.17.2 of bundler calls functions that are deprecated and soon to be removed from Ruby. Using bundler in this repo outputs warnings saying this.

Close #3503
