Summary
The transaction build command can no longer build Tx for different eras than is the current network era, e.g. Alonzo-era Tx on Babbage network era.

cardano-cli transaction build --tx-in "96427198dfb62589e6223a07b9504ccca7dca89ccace3cc54e3344908dd71694#1" --tx-out "addr_test1vrnrd6p72nx0qwrqwdfm6ken9h0lte927mfqqsq05g4pwps9pw247+1500000" --change-address addr_test1vqw2078dw2kl49f5vquxxyhd5ly53cu36zu67u8t80xn4cqmjdsy4 --out-file test_build_transfer_funds_ci0_gcw_tx.body --alonzo-era --testnet-magic 42

Command failed: transaction build  Error: The era of the node and the tx do not match. The node is running in the Babbage era, but the transaction is for the Alonzo era.

Seems to be introduced by PR #4446.

Expected behavior
It is possible to build Alonzo-era Tx on Babbage by specifying --alonzo-era argument.
