The SAFE_TX_TYPEHASH value is wrong for < 1.0.0 Safe versions

[pcaversaccio]

Safe multisig versions < 1.0.0 use a legacy (i.e. the parameter value baseGas was called dataGas previously) SAFE_TX_TYPEHASH value. Starting with version 1.0.0, baseGas was introduced: safe-global/safe-smart-account#90.

safe-core-sdk/packages/protocol-kit/src/utils/eip-712/index.ts

Lines 39 to 52 in 014f365

	SafeTx: [
	{ type: 'address', name: 'to' },
	{ type: 'uint256', name: 'value' },

Fwiw, I shipped support now for Safe versions 0.1.0 in my Bash script: pcaversaccio/safe-tx-hashes-util#9
