Separate MIN_DEPOSIT_CLI_VERSION validation from deposit data validation

[hwwhww]

To address #532

Reporting by @barnabasbusa

When using older deposit-cli version that less than MIN_DEPOSIT_CLI_VERSION, the error message is confusing

The MIN_DEPOSIT_CLI_VERSION validation should be handled separately from deposit data validation:

staking-launchpad/src/pages/UploadValidator/validateDepositKey.ts

Lines 72 to 81 in d25870f

	// check the deposit-cli version
	if (
	compareVersions.compare(
	depositDatum.deposit_cli_version,
	MIN_DEPOSIT_CLI_VERSION,
	'<'
	)
	) {
	return false;
	}
