Handle win style CRLF newlines in vault text (#27590)

Browse source 
When parsing a vaulttext blob, use .splitlines()
instead of split(b'\n') to handle \n newlines and
windows style \r\n (CRLF) new lines.

The vaulttext enevelope at this point is just the header line
and a hexlify()'ed blob, so CRLF is a valid newline here.

Fixes #22914
