[xcm-builder] Replaced deprecated CurrencyAdapter with FungibleAdapter (

paritytech#3287)

I found out during the cleanup of this deprecation message in the
`polkadot-fellows` repository that we deprecated `CurrencyAdapter`
without making the recommended changes.


## TODO
- [ ] fix `polkadot-fellows` bump to 1.6.0
polkadot-fellows/runtimes#159
