correct td command quotation mark position

[superewald]

The example of loading types from string at Loading Types seems to have wrong quotation marks.

[0x000051c0]> "td struct foo {char* a; int b;}" does nothing for me (using rizin 0.5.0 @ windows-x86-64). [0x000051c0]> td "struct foo {char* a; int b;}" works (note the quotation mark being moved after td command).
