[ts-sdk] Remove iota-bridge related EndOfEpochTransactionKind variants #7245
Description
In #6863 the iota-bridge and all the related code has been removed from rust crates.
This means that the EndOfEpochTransactionKind variants BridgeStateCreate and BridgeCommitteeInit were removed from the rust sdk and thus from the openrpc spec (such variants were never used on a live network, because the bridge protocol flag was never enabled).
These changes should be reflected in the TS SDK.
(Additionally, that #6863 removed bridge flag (never enabled) and disabled bridge_should_try_to_finalize_committee flag, but this should not require changes to the TS SDK.)
