Problem: versionDB migration does not support pebbleDB

[GAtom22]

Describe the bug
At the moment, versionDB migration procedure does not support pebbleDB

~ $ evmosd changeset dump "/home/evmos/.evmosd/data_rocks" --home "/home/evmos/.evmosd/" --log_level "debug"
Error: unknown db_backend pebbledb, expected one of goleveldb,memdb,rocksdb

Would be great to add support for this DB

To Reproduce
Steps to reproduce the behavior:

1. Start a node with pebbleDB.
   Usually this requires to replace the cometbft-db module

go mod edit -replace github.com/cometbft/cometbft-db=github.com/notional-labs/cometbft-db@pebble
go mod tidy
COSMOS_BUILD_OPTIONS=pebbledb make build

2. Run a node with this config and store some data
3. Perform the migration procedure to versionDB

I think the dump cmd use the cometbft-db db opener as usual, maybe sth wrong with the cometbft-db replacement?

Closing because this issue is not related to versionDB, but related to the cometbft-db dependency
